Answer:
A. 2.9π(9²)
Step-by-step explanation:
You are expected to know that the area of a circle is given by the formula ...
A = πr²
and that r in the formula represents the radius of the circle, half the diameter.
The area of the circular base of the cylinder is the area of a circle with a radius of 9 feet. It will be ...
A = π(9²)
When that is multiplied by the height of the cylinder to find its volume, you have ...
V = Bh
V = (π(9²))(2.9)
This can be rearranged to match the form in answer choice A:
2.9π(9)²
Answer:
Step-by-step explanation:
hello,
how many students ? 14 + 2 + 5 +3 = 24
how many students who had C and S ? 14 + 2 + 5 = 21
so P(C∪S)=21/24=(7*3)/(8*3)=7/8
hope this helps

Answer:
18/49
Step-by-step explanation:
Invert and multiply:
3/7 ÷ 1 1/6 = (3/7) ÷ (7/6)
