## Homework Statement

Ive been trying to find the Inertia and Kinetic energy of the sun. I have a feeling im using the wrong formulas to obtain the answer.

Mass of sun 2*10^30kg

Radius of sun 700*10^6 m

t spin = 26 days

the answers should be

I = 4.0 * 10^98

K energy = 1.5 * 10^16

## Homework Equations

I=(2/5)*M*R^2

K= (1/2)M*(ω^2)*(r^2)

ω = 2pi/t

## The Attempt at a Solution

If someone knows how to do this i would really appreciate it.
