Question

Find the volume and surface area

a sphere with the great circle having an area of 26pi

Answer 1

great circle of a sphere = largest circle made at the diameter of the sphere.
Radius of great circle = radius of sphere

Answer 2

Area of circle = \(\pi r^2\)
use this to get the area of sphere

Volume of sphere = \({4\over 3}\pi r^3\)
Surface area of sphere = \(4\pi r^2\)

Answer 3

idk what is the radius

Answer 4

Area of circle = 26 pi
plug into the equation
\[26\pi=\pi r^2\]solve for r

Answer 5

r=5.1

Answer 6

this is also the radius of the sphere.
plug this radius in the formulae for the volume and surface area

Answer 7

thank u :)
