Answer:

area of a circle = 1808.64meters²

Step-by-step explanation:

given that ,

π = 3.14

circumference = 150.72meters

calculate the area of the circle.

to calculate the circumference of a circle

recall,

circumference of a circle = 2πr

circumference of a circle = 2 x 3.14 x r

circumference of a circle =  6.28r

150.72meteras = 6.28r

divide both sides by 6.26

150.72meters/6.28 = 6.28r/6.28

24meters = radius

radius = 24 meters

now to calculate the area of the circle

recall the formulae for finding the area of a circle is given to be = πr²

area of a circle = πr²

area of a circle = 3.14 x ( 24)²

area of a circle = 3.14 x 576meters²

area of a circle = 1808.64meters²

The circumference of a circle is 9π m. What is the area, in square meters? Express your answer in terms of π π
storchak [24]

Answer:

A = 20.25π sq meters

Step-by-step explanation:

C = 2πr

9π = 2πr

divide π from each side to get:

9 = 2r

r = 9/2 or 4 1/2

A = πr²

A = π (4.5²)

A = 20.25π
