Question

the radius of a circle with area 200.96 in^2

Answer 1

Answer:

8 in.

Step-by-step explanation:

Area = pi r^2   where r is the radius

pi r^2 = 200.96

r^2 = 200.96 / pi

r^2 = 63.9676

r = sqrt 63.9676

= 7.998

Answer 2

Answer:

The radius of the circle with area 200.96 units square will be 8 units.

Step-by-step explanation:

1) Consider a circle with radius r units and area A = 200.96 units square

2) The area of the circle is given by

$A = \pi {r}^{2}$ ...(1)

We have

A = 200.96

π = 3.14

Putting the values of A and π in eq (1),

$200.96 = 3.14 {r}^{2}$

${r}^{2} = \frac{200.96}{3.14}$

${r}^{2} = 64$

$r = \sqrt{64}$

$r = 8$

Therefore the radius of circle is 8 units

Therefore the radius of circle with area 200.96 units square is 8 units.
