Answer:
The exact volume is 192π
1)You multiply the radius squared by the height so 4^2 times 12
2)38.4π because you take the volume of the cylinder and multiply it by .20
Step-by-step explanation:
Answer:
The approximate circumference is 62.8 mm
Step-by-step explanation:
Circumference is basically the perimeter of the circle
Circumference is given by

Here the diameter is 20 mm, so the radius will be half of diameter = 10 mm
Substituting the given values, in above equation, we get -
Circumference =
mm
The approximate circumference is 62.8 mm
Yes because 1 1/4 + 1 1/2 = 2 3/4
The area of the room must equal the sum of the areas of the tiles...
20*30=n(2*3)
600=6n
n=100
So 100 tiles are needed.
