Find the volume of the sphere that has a surface area of 720 in2. Round your answer to the nearest tenth.

1816.7

Step-by-step explanation:

Surface area = 4πr² = 720

r = √(720/4π)

Volume = 4/3×π×r³

= 1816.7

Volume of sphere = 1817 inch³

Step-by-step explanation:

Given:

Surface area of sphere = 720 inch²

Find:

Volume of sphere

Computation:

Surface area of sphere = 4πr²

720 = 4(3.14)r²

720 = 12.56r²

r² = 57.32

radius = 7.57 inch

Volume of sphere = (4/3)(π)(r)³

Volume of sphere = (4/3)(3.14)(7.57)³

Volume of sphere = 1817.09

Volume of sphere = 1817 inch³

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
