Question

Find the area of the circle. I need help on this. I don't really understand A. 78.5 square feetB. 25 square feetC. 31.4 square feetD. 5 square feet

Answer 1

To find the area of the circle, we will use the formula below;

$A=\text{ }\pi r^2$

where pie = 3.14

r= radius = 10/2 = 5

substitute the values into the formula

$A=\text{ 3.14 }\times5^2$

$A=\text{ 3.14}\times25$$A=78.5\text{ square f}eet$
