Answer:
A. you need 2 1/2 ounces
B. you need 73,9 milliliters
Step-by-step explanation:
A
We have the ratio 1/2 ounces per gallon
And the mop bucket holds 5 gallons
Then we need to multiply 1/2*5
we got 2 1/2 ounces of desifectant per 5 gallons
B
1 ounces equal 29,57 milliliters
if we have 2 1/2 ounces then we multiply 2,5 *29,57
the answer is 73,9 milliliters
First you need the formula for SA of a cylinder: SA = 2(πr^2) + 2πr*h
(area of the top and bottom circles plus the side)
Then plug your values into the equation and rearrange to make h the subject:
1470.3 = 2π13^2 + 2π*13*h
26πh = 1470.3 - 338π
h = (1470.3 - 338π)/26π
=5.00042...
so h is approximately 5 units :)
The answer to this question is B!
