The surface area of a sphere is 64π square inches. Which equation can be used to solve for the radius of the sphere?
64π = 4πr
64π = 2πr3
64π = 2πr2
64π = 4πr2

Respuesta :

Surface of a sphere: S=64π square inches

Equation of the Surface of a sphere:
S=4πr^2
Replacing S by 64π:
64π=4πr^2

Answer: Fourth option 64π = 4πr^2

The surface are of a sphere is given by this equation:

[tex]A=4 \pi r^{2} [/tex]

Given that we have a sphere with a surface area of 64π. Then, to solve the radio of the sphere we use this equation:

[tex]64 \pi =4 \pi r^{2} [/tex]
