Answer:
5^2 = 100
100 x 3.14 = 314
Now we multiply by 20 since it's the height.
314 x 20 = 6,280 cm^3 is your answer.
Formula of cylinder:
H x πr^2
Height x pi(3.14 or 22/7 depending what they tell you to use for pi) x radius being squared (your radius is half of your diameter or given radius).
Answer:
No
Step-by-step explanation:
For a number to be divisible by 10 it has to end in 0.
The answer is n = d/4 + 1/2
60x - 150 = 30
60x - 150 + 150 = 30 + 150
60x = 180
60x/60 = 180/60
x = 3
