Answer:
b) Diameter = 6 inches and height 3 inches
Step-by-step explanation:
we are given the Volume of the cone as 28 and asked to determine the possible combination from the options. In these two options there are two different heights given . We will determine the radius or diameter for these two heights and thus can find the possible correct combination.
The two heights are
h= 3 in and h = 6 in
Volume V=28 c in
Part 1: When height h = 3 in
Formula for Volume of a cone is give as
replacing the values
Diameter D = 2r = 5.96 ≈ 6 in
Hence Option B) is correct in first part. Let us see for the next part
Part 2:
V=28 c in , h= 6 in
Formula for Volume of a cone is give as
replacing the values
Diameter D = 2r = 4.22 inches
Hence none of the last two options are close to the answer.
Hence our final answer is b) Diameter = 6 inches and height 3 inches
Answer:
1 17/20
Step-by-step explanation:
Put 185 over 100. Then, Simplify. Divide 180 and 100 by 5. 180 ÷ 5 = 37 and 100 ÷ 5 = 20. Then, divide 37 by 20. Write down the the quotient as the whole number and the remainder as the numerator.
So
10^x times 0.02=20
divide both sides by 0.02
10^x=1000
10^3=1000
answer is 3rd power of 10
