Answer: The height is 5 inches.
Step-by-step explanation:
The surface area of a cylinder uses the formula A= 2
rh + 2r^2
so as you could see in the equation there is an h in in it which re
presents the height and we know the diameter is 2 so we need to find the radius and the radius is 1 because half of 2 is 1 or half the diameter is the radius.
Now put the radius into the equation and and solve for the height and as you could see the surface area is left in terms of pi.
12 = 2 * 1 * h + 2 * 1
12= 2 * h + 2
-2 2
10 = 2h
h =5
Answer: 0.10g/cm^3
Step-by-step explanation:
We can compare this with the volume of a football (soccer ball) – which has a radius of around 10.5cm, therefore a volume of around 4800 cubic centimeters.
Answer:
20
Step-by-step explanation:
if its one fifth than we can just multiply by 5
4 x 5 = 20
hope this helps : )
Answer:
30% of 150 is 45
Step-by-step explanation:
30% = .3 x 100
So take 30% out of its percentage form
then multiply .3 and 150
150 x 0.3 = 45
Henceforth, 30% of 150 is 45
