Answer:
3375/64
Step-by-step explanation:
You make the fraction into a improper fraction
3 3/4=15/4
You cube the top and bottom
15^3/4^3=3375/64
Thus
answer-3375/64
you just need to divided 3 by 9 and it will be 3 or you can divide 6 by 18 and it will be the same so the unite rate is $3
The answers have square roots among the choices so we probably shouldn't use that calculator button.
We can't just apply the area of the trapezoid formula
where b is the bottom base, t the parallel top, and h the height, because we don't know the top t.
It will be 10 less the leg of that right triangle, which we calculate as
Now we can apply the trapezoid formula. We have
Choice b
I have the same question and I have no idea sorry
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.
