Answer:
12.4 cm
Step-by-step explanation:
Use the sphere volume formula, V = r³
Plug in the volume and solve for r, the radius:
V = r³
7961 = r³
1900.55 = r³
12.39 = r
So, the radius of the sphere is approximately 12.4 cm

Answer:
Step-by-step explanation:
Use the formula to find the sum of the angles in a polygon, given <em>n</em> sides. This formula tells us the angles of this pentagon must add to 540 (
).
So, we can setup an equation:
Solve for z:
Combine like terms
Subtract 200
Divide by 5
Therefore, the value of z = 68.
Answer:
Area of the base =
Step-by-step explanation:
We know that volume of rectangular prism = (Area of base) x (Height)
or [Area of base] = [Volume]/[Height]
So basically we need to divide given area by given height to find the answer.
given height is (x+2) that means (x+2) must be factor of volume equation
or x=-2 must be root of volume equation so write down coefficients of volume equation then we divide by -2 as shown in attached picture.
Last digit on the right is always remainder.
Remaining coefficients {2, 5, -18} will give the area equation:
Hence final answer is:
Area of the base =
