Answer: 7/5
Step-by-step explanation:
It is 9/4π ft².
Since the central angle is 40°, this is 40/360 = 1/9 of the circle.
The area of the circle is given by A=πr²; since r=9/2, we have
A=π(9/2)² = 81/4π
Multiplying this by 1/9,
81/4π(1/9) = 81/36π = 9/4π
Answer:
h=3
Step-by-step explanation:
divided the 21 by the 7
First, I like switching the sides so that the equation looks like this: bv/k=M
Then get bv alone by multiplying both sides by k: bv=kM
After that, divide both sides by b to get v by itself: <u>v=kM/b</u>
I hope this helps you!
