Answer:

452.16 m²

Step-by-step explanation:

Given :-

Radius = 12 m

To Find :-

Area

Formula Required :-

Area (circle) = πr²

Solving :-

Area = 3.14 x 12 x 12

= 3.14 x 144

= 452.16 m²

Solution :-

452.16 m²

Answer:

144

Step-by-step explanation:

A=πr^2

Where:

A

is the Area of the Circle: what we are solving for in this problem.

r

is the Radius of the Circle: 12 meters for this problem

Substituting and calculating

A

gives:

A=π(12)^2m^2

A=π144m^2

A= 144m^2

This circle would have an area of 144 square meters.

Answer:

2/14, 4/28, 5/35, 7/70 or just 2/14

Step-by-step explanation:

Multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14

And multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21. So 2:14 and 3:21 are two ratios that are equal to 1:7.

The volume of the vase obtained by revolving the curve y=2+sinx from x=0 to x=5 about the x-axis is 80.115 unit³

Volume is the amount of space occupied by a three dimensional shape or object.

The volume V is given by:

[tex]V=\pi \int\limits^0_5 {(R^2-r^2)} \, dx \\\\R = 2+sinx;r=0, hence:\\\\V=\pi \int\limits^0_5 {(2+sinx)^2} \, dx\\\\V=80.115\ unit^3[/tex]

Answer:

p = 1

Step-by-step explanation:

2/5 + p = 4/5 + 3/5p

2/5 + p = 3p/5

2/5 + p = (4 +3p)/5

2 + 5p = 4 + 3p

5p = 4 + 3p - 2

5p = 3p + 2

5p - 3p = 2

2p = 2

p = 1

Answer:

They should leave Carlo's house by 4:20 PM

Step-by-step explanation:

The movie starts at 8:10 pm, they want to arrive 20 minutes before the movie starts

20 minutes before 8:10 pm = 7:50 pm.

Hence, they should arrive by 7:50 pm

Duration of their activities before the movie is calculated as:

They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater.

: 1 hour + 1 hour 15 minutes + 20 minutes + 45 minutes + 10 minutes

= 2 hour 15 minutes + 75 minutes

= 2 hour 15 minutes +1 hour 15 minutes

= 3 hours 30 minutes in total.

The time they are meant to leave is calculated as:

7:50 pm - 3 hours 30 minutes

= 4:20pm

Answer:

a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?

Step-by-step explanation:

Cost minus the charge which is 8 dollars minus 5.50 is the difference in which you divide 80 by it. 8-5.50= 2.5.     80 divided by 25 = 32. Hope this is the answer you're looking for.

Answer:

Step-by-step explanation:

option B

Complementary angles add up to 90°

m∠A + m∠B = 90

30 + 2x + 10 = 90

       2x + 40 = 90

To find the value of x, we have to isolate x. To isolate x, first we have subtract 40 from both sides.

2x = 90 -40

2x = 50

Now, divide both sides by 2

x = 50/2

x = 25°

∠B = 2x + 10

      = 2*25 + 10

    = 50 + 10

∠B = 60°

Step-by-step explanation: The graph shows the zeros to be -1, +2 (multiplicity 2), and +3.

When b is a zero, (x-b) is a factor. Then the factors of the function shown are ...

 f(x) = (x -(-1))·(x -2)·(x -2)·(x -3)

 f(x) = (x -2)^2(x +1)(x -3)

Answer:

t₁ = 14

d = -2

Step-by-step explanation:

Given :-

t₆ = 4

t₁₀ = -4

To Find :-

t₁ and d

Solving :-

t₆ = t₁ + 5d = 4   -(1)

t₁₀ = t₁ + 9d = -4 -(2)

(2) - (1)

4d = -8

d = -2

t₁ + 5(-2) = 4

t₁ = 14

Solution :-

t₁ = 14

d = -2

Answer:

56.6 ft

Step-by-step explanation:

→ Perimeter = All sides added together

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

Answer:

56.6

Step-by-step explanation:

Perimeter is just adding all the outer value of an shape

So we add all the answers

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

but there is easier way

5.2 x 2 = 10.4

7.7 x 6 = 46.2

10.4 + 46.2 = 56.6
