Exercise 27 Page 65

To find the area, use the formula A=π r^2.

153.9 ft^2

Practice makes perfect
To find the area of a circle, we use the following formula. A=π r^2 We know that this circle has a radius of 7 feet, so we can substitute 7 for r in the formula.
A=π r^2
Substitute

r= 7

A=π ( 7)^2
CalcPow

Calculate power

A=π(49)
Multiply

Multiply

A=153.93804
RoundDec

Round to 1 decimal place(s)

A≈ 153.9
The area is approximately 153.9 ft^2.
