Answer:
a = - 2
Step-by-step explanation:
calculate the slope of the 2 given points and equate to 0.75
m = 
with (x₁, y₁ ) = (4, a ) and (x₂, y₂ ) = (8, 1 )
m =
= 
then equating
= 0.75 ( multiply both sides by 4 to clear the fraction )
1 - a = 3 ( subtract 1 from both sides )
- a = 2 ( multiply both sides by - 1 )
a = - 2
Step-by-step explanation:
The volume for cylinder is V= πr2h
It gives is the volume of the cylinder is 720 π
We can cancle the pi from the Volume and the formula.
After that let h = 20.
