Question

A circle has an inside area of 13,266.5 square yards. What is the radius of the circle? Use 3.14 to approximate pi

Answer 1

Answer:

65

Step-by-step explanation:

13,266.5 yds2 = 3.14 • (65 yds)2

Answer 2

We have been given some information about a circle whose area is 13266.5 square yards. And we are advised to use value of π =3.14.

Now we need to find the radius of the circle so we can use formula of area of the circle which is :

$Area = \pi r^2$

$13266.5 = 3.14 r^2$

$\frac{13266.5}{3.14} = r^2$

$4225 = r^2$

take square root of both sides

65 = r

Hence final answer is radius of the circle = 65 yards.
