Circumference=diameter x pie

=(17.5×2)×pi

=35pi

Answer:

35π cm

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius ) , then

C = 2π × 17.5 = 35π cm

Answer:

9ft

Step-by-step explanation:

The top of a ladder is placed against the side of a house. The ladder is 15ft long and the wall is 12ft high. How far from the wall will the base of the ladder be positioned if the top of the ladder meets the top of the wall.

We solve this question using Pythagoras Theorem

c² = a² + b²

Height of the wall = Opposite side = b = 12ft

Length of the ladder = Hypotenuse = c = 15ft

Distance between the wall and the base of the Ladder = Adjacent = a

Hence:

15² = a² + 12²

a² = 15² - 12²

a = √15² - 12²

a = √81

a = 9 ft

Therefore, the wall will be 9ft from the base of the ladder , if the top of the ladder meets the top of the wall

Convert 1 hour into minutes and divide 15/60

The answer is 1:4

Step-by-step explanation:

The values will vary by a percentage of 60%.

Finding the difference between two values in a time series, dividing that difference by the initial value, and multiplying by 100 are used to determine the percentage change between the two values.

Given two values 500,000 and 800,000

From the general formula of percentage change

percentage change = (final value - initial value)/ initial value * 100

Percentage change = (800,000 - 500,000)/500,000* 100

Percentage change = 60

Therefore, the percentage change of the given values will be 60%.

The length of BC is 15 units.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Given a right angled triangle ABC.

Given that angle C is right angle.

Side AB is the hypotenuse, AC is the base and BC is the altitude.

Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.

Using the theorem,

(AB)² = (AC)² + (BC)²

(BC)² = (AB)² - (AC)²

        = 17² - 8²

        = 289 - 64

        = 225

BC = √225 = 15 units

Hence the side length of BC is 15 units.
