Answer:
Step-by-step explanation:
the surface area = area of the 4 faces+ area of the 2 bases
4 *(15*8) + 2*( 8*6) = 480+96 = 576 cm²
if the length of the faces tripled, the two bases remain unchanged because the prism just gets taller on the same bases.
Answer:
About 1,237 cubic feet.
Step-by-step explanation:
The first step is to know the formula for the volume of a cylinder.
V = pi * r^2*h
You have all the numbers needed because 7ft is the height and the half the diameter (or half of 15) is 7.5. so:
V = pi * 7.5^2 * 7

10 1/2 - 1 1/2 = 9
For this case we must solve the following quadratic equation:
Subtracting 50 from both sides of the equation we have:
Applying square root to both sides of the equation we have:
We have two real roots:
