Question

2) A circle has a diameter of 10 feet. What is the area of the circle, in square feet?

Answer 1

Answer:

Area = 78.5 square feet

Step-by-step explanation:

Formula for area of a circle: A = pi r^2 or area = pi times radius squared

So the diameter = 10 feet

And radius is half of the diameter so radius = 5 feet

A = pi x 5 squared

A = pi x 25

A = 78.5 square feet

Answer 2

Answer:

A = 78.5 $ft^{2}$

Step-by-step explanation:

A = π$r^{2}$

diameter = 10

radius is half of 10 = 5

A = 3.14 x $5^{2}$

A = 3.14 x 25

A = 78.5 $ft^{2}$
