Question

The circumference of a circle is given by the formula C = 2 πr Find r if the circumference is 88 meters and π is 22/7

Answer 1

Answer:

radius= 1.272727 meters.

Step-by-step explanation:

We have given the circumference of a circle :

C = 88 meters.

We have to find the radius of circle.

We know the formula of circumference that is:

C = 2πr

Here C =88 and π = 22/7.

Putting these values in above formula we get,

88 = 2(22/7)r

88 = (6.285714)r

r = 88/ (6.285714)

r= 1.272727 meters.

Answer 2

Answer: 1.27 m

Step-by-step explanation:

To solve this problem you onlly need to solve dor the radius from the formula of the circumference given in the problem above, as you can see below:

$C=2r\pi \\r=C/2\pi$

Substitute values into the formula, therefore you obtain that the radius of the circle is the shown below:

$r=\frac{8m}{2*\frac{22}{7}}\\r=1.27m$
