Answer:
-60 im pretty sure this is it
V=4/3πr^3
36π=4/3πr^3
3/4(36π)=(4/3πr^3)3/4
27π=πr^3
π(27π)=r^3
27=r^3
square root
r=3
s.a=4πr^2
s.a=4π(3^2)
s.a=4π(9)
s.a=36π
I believe the answer is b
Answer/Step-by-step explanation:
An equation that describes the relationship can be written as
.
Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

Substitute m = 70 into 
The equation would be:

This equation can be interpreted as follows:
The heart's resting rate is 70 beats each minute.
3 divided by x to find the what the amount of x is
