Question

PLEASE HELL!! WILL MARK BRAINLIEST AND THANK YOU!!! IM DESPERATE!!!

Find the area. You answer will be a decimal.

_________ ft²

Answer 1

Answer:

26.4 ft^2 (1 d.p.)

Step-by-step explanation:

$area \: of \: circle = \pi {r}^{2}$

Since it is given that r, the radius of the circle, is 2.9 ft,

area of circle= π(2.9)^2= 8.41π= 26.4 ft^2 (1 d.p.)

Answer 2

Answer: A≈26.42

Step 1: Write equation for circle area

A=πr ²

Step 2: Substitute radius

A=π2.9 ²

Step 3: Solve

A= π2.9 ²

A= π•8.41

A≈26.42
