Okie, when you are talking about area, you will have units of course! :-)
So, square units are the units in which describe the area. Let's take a rectangle slab of paper that is 2 inches by 4 inches. Yes, the answer is 8, but what are the units. It is inches squared! Squared units are the units of area.
I hope this helps :-)
Answer:
The answer is 390 × pi.
Step-by-step explanation:
Big cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 9^2 x 15
= 1272.3 cubic inches
Small cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 3^2 x 5
= 47.1 cubic inches
1272.3 - 47.1 = 1225.2 cubic inches
1272/3.14 ≈ 390
The answer is 390 × pi.
