Volume of cone = (1/3)pi*r²h
56.52 = (1/3)*3.14*r²*6
56.52/(2*3.14) = r²
9 = r²
r² = 9
r = √9
r = 3
Diameter = 2*r = 2*3 = 6 inches. b.
Answer:
33, 39, 45, 51
Step-by-step explanation:
The general term of an arithmetic sequence is given by the formula ...
an = a1 + d(n-1) . . . where a1 is the first term and d is the common difference
Comparing this formula to the one you are given, you see that ...
a1 = 33, d = 6
This means the first term is 33, and each successive term is 6 more than the previous one. The first 4 terms are ...
33, 39, 45, 51
Answer:
28%
Step-by-step explanation:
We get 30% off the original price
The new price is (100-30) = 70$ of the original price
Let x = the original price
The new price is .7x
Now get get an additional 60% off. We pay (100-60) = 40 percent of the price
Take .7x * .4
The new price is .7*.4 x
.28x
This is 28 percent of the original price x

Answer:
-220
Step-by-step explanation:
(11×4)×(4²-6×4+3) (calculate the power)
(11×4)× (16-16×4+3)
44×(16-24+3)
44×(-5)
-44×5
=-220
