The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14. Rewrite the equation to solve for the radius of the sphere if you know the sphere’s surface area. Then estimate the radius of a sphere given a surface area of 500 meters2.
I need to understand how to use combining like terms for this problem
i understand that you need to add each number to each side
but i don't know the correct order i know the set up, just not the right number places
S=4πr^2 divide everything by 4π S 4π =r^2 take the positive square root of both sides, (we are working with length so negative does not make sense) so S 4π − − √ =r now let S=500
