The radius of this ball is 15 inches. which equation gives the ball's surface area, in square inches?

Best to look up the formula for the surface area of a sphere and then find it:

A = 4πr^2, where r is the radius of the sphere.  Then,

A = 4π(15 in)^2 = 4(3.14)(225 in^2) =  2826 in^2 (answer)

This is represented by the formula given in the lower left.

move it to the other side

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
