Find the circumference of a circle whose area is ft^2
A.
B.
C.
D.

B

Step-by-step explanation:

Area = pi × r²

24pi = pi × r²

r² = 24

r = sqrt(24)

r = 2sqrt(6)

Circumference = 2pi × r

2pi × 2sqrt(6)

(4sqrt(6))pi

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
