Answer:

339.3m²

Step-by-step explanation:

Formula is volume= X radius² X height

First find radius, which is 1/2 of the diameter.  6/2= 3 is the radius

Then set up the equation: ()(3²)(12)

Put into calculator to get 339.3 (rounded to the tenths)

The volume of the cylinder will be 339.12 cubic meters.

Let r be the radius and h be the height of the cylinder. Then the volume of the cylinder will be given as,

V = π r²h cubic units

The cylinder has a base diameter of 6 m and a height of 12 m. Then the radius of the cylinder is calculated as,

r = d / 2

r = 6 / 2

r = 3 m

Then the volume of the cylinder is calculated as,

V = 3.14 x 3² x 12

V = 339.12 cubic meters

Answer:

The team can buy 5 basketballs

Step-by-step explanation:

215 / 39 = 5.51

or

5 with a remainder of 20 dollars.

We simply cannot buy 0.51 of a basketball, unless you bring a saw...

Answer:

they can buy 5 balls, and they will have 20 dollars left over.

Step-by-step explanation:

to solve, divide 215 by 39, so 215/39 which gives us 5.512. and since we cant have half of a ball, and we do not have enough capital to buy another ball, we settle for the 5. it isnt important, but to get the leftover money, just multiply 5 by 39, or 5x39 to get 195. then subtract the original value to get 20 dollars.

Answer:

The correct answer is 4 sec

Step-by-step explanation:

The soccer ball returns to the ground after 4 seconds, got from solving the quadratic function y = -16t² + 64t.

A polynomial function is a relation where a dependent variable is equal to a polynomial expression. A polynomial expression is an expression including numbers and variables, where variables are raised to non-negative powers.

The general form of a polynomial expression is:

a₀ + a₁x + a₂x² + a₃x³ + ... + aₙxⁿ.

The highest power to a variable is the degree of the polynomial expression.

When degree = 2, the function is a quadratic function.

When degree = 1, the function is a linear function.

We are given a quadratic function representing the height of the ball after a goalie kicks it. The function is y = −16t² + 64t, where y is the height in feet of the ball at time t seconds.

We are asked how long it takes for the soccer ball to return to the ground.

To calculate the time for the ball to return to the ground, we take height y = 0.

Our equation therefore is,

0 = -16t² + 64t

or, 16t² - 64t = 0

or, t² - 4t = 0

or, t(t-4) = 0

∴ Either, t = 0; Or, t-4  = 0 ⇒ t = 4.

∴ The height of the ball is 0 when time t is 0 and 4. Time 0 is before the goalie kicked the ball, so we take t = 4 seconds.

∴ The ball takes 4 seconds to return to the ground.

Answer:

43.1

Step-by-step explanation:

Similar shapes have sides of the same proportions. This means that one shape is just an enlargement of the other.

In this case, triangle MNO is an enlargement of triangle JKL so we can work out a scale factor.

To work out the scale factor, we can do 58.8 ÷ 15 = 3.92. To find side NO, all we have to do is multiply 11 by 3.92 to get 43.12 ≈ 43.1 (rounded to the nearest tenth).

The equation is (1/3-6m)-(1/4n-8).The equation's difference is -6m-1/4n+25/3.

Given that,

The equation is (1/3-6m)-(1/4n-8)

We have to find the difference of the equation.

What is difference?

Difference in mathematics is produced by one of the most important mathematical operations, which is obtained by deleting two numbers. It displays the difference between two numbers. To determine how many numbers are between the two supplied numbers is the goal of finding the difference in math.

The difference in mathematical notation is minus (-).

To difference between whole numbers and natural numbers, take the following steps:

The values are initially arranged vertically according to their place values. Additionally, make sure that the larger number is on top and the smaller one is at the bottom.

Starting at the ones place, begin removing the numerals.

Take the equation,

(1/3-6m)-(1/4n-8)

Taking least common multiple.

(1-6×3m)/3-(1n-8×4)/4

By multiplication

(1-18m)/3-(n-32)/4

Taking the least common multiple.

4(1-18m)-3(n-32)/3×4

By multiplication

(4-72m-3n+96)/12

Now by adding

(-72m-3n+100)/12

By dividing

-6m-1/4n+25/3

Therefore, The difference of the equation is -6m-1/4n+25/3.

Answer:

29√5

Step-by-step explanation:

Given:

Total number of girls in her class = 16

Total number of boys in her class = 14

To find:

The number of different ways of choosing one girl and one boy.

Solution:

We have,

Total number of girls = 16

Total number of boys = 14

So,

Total number of ways to select one girl from 16 girls = 16

Total number of ways to select one boy from 14 boys = 14

Now, number of different ways of choosing one girl and one boy is

[tex]16\times 14=224[/tex]

Therefore, the required number of different ways is 224.

a. The number of  different ways of choosing one girl and one boy is 226

Total number of ways to select one girl from 16 girls = 16

Total number of ways to select one boy from 14 boys = 14

So, the number should be

[tex]= 16 \times 14[/tex]

= 224
