X-intercept: (3.5,0)
Y-intercept: (2.5,0)
2 4/10
2 2/5
That's the answer
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
The answer would be s=-60
