Surface area of a sphere is 615.752 m2, what is the volume of the sphere? a) 1436.76 m2 b) 1436.76 m3 c) 2463.01 m2 d) 2463.01 m3

B

the volume (V) of a sphere = πr³

We require to know the radius r to calculate the volume

using surface area of a sphere = 4πr² = 615.752

divide both sides by 4π

r² = = 49.0248...

take the square root of both sides

r = ≈ 7, hence

V= × π × 7³ = 1436.76 m³ → B

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
