This is the expression simplified:
Step-by-step explanation:
V=pi×r^2×h
36pi =pi × (3)^2 × h
36pi ÷ pi×9 = h
4cm^2 = h
Answer:
200
Step-by-step explanation:
Let's call the number x :
12.5% of x = 25
Changing 12.5% into decimal would be 0.125
Now we have the equation :
0.125x = 25
Divide both sides by 0.125 to make x the subject :
x = 25 ÷ 0.125
x = 200
To check we can substitute this value into the question :
12.5% of 200 = 25
Hope this helped and have a good day
