Put the number over each the total that was added then, divide the bottom number to into the top number
Answer:
Step-by-step explanation:
8.5*7.5 = 63.75
12/15 = x/100
Multiply 12 x 100 to get 1,200/15 is 80.
Because 25 x 4 = 100, you divide 80 by 4.
Your answer is 20.
Answer:
5.4 m
Step-by-step explanation:
18/3 = x/0.9
0.9(18/3) = x
x = 5.4
Answer:
V = 1200π
Step-by-step explanation:
Volume of a cylinder formula:
Let's find the height of the cylinder by multiplying 20 cm by 3/5.
The radius is 1/2 of the diameter, so:
Substitute 12 for h and 10 for r into the volume formula.
Simplify.
- V = π * 100(12)
- V = π * 1200
The volume of a cylinder, in terms of π, is V = 1200π.
