Answer:
sphere volume = 3052.1 in³
Step-by-step explanation:
sphere volume = 4/3πr³ = 4/3(3.14)(9³) = 3052.1 in³
Answer:
104 yd^2.
Step-by-step explanation:
Area of the 2 circles = 2 * π r^2
= 2 * π * 4^2
= 32 π yd^2.
Area of the side of the cylinder = 2 π r h
= 2 π * 4 * 9
= 72 π yd^2.
Total surface area = 32 + 72
= 104 yd^2.
15 - x = 2(x + 3)
15 - x = 2x + 6
15 = 3x + 6
9 = 3x
3 = x
x = 3
Answer:
Square root of 98
Step-by-step explanation:
Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38
