πr(2r) + πr(squared) = does anybody know how am i supposed to solve this problem??

Question

theres no numbers given at all!

Answer 1

pie times radius (2 time radius) plus pie times radius squared

If my high school math memory is correct...

Answer 2

There are plenty of numbers.

Distribute the 2r

2πr^2+πr^2

=3πr^2

Answer 3

It's not an equation, as you have nothing on the right of the equals, and therefore cannot be solved.

And solve for what?

.

Answer 4

This is an expression, not a full equation, so there's nothing to solve.

If you want to SIMPLIFY this expression, you can:

πr(2r) + πr^2 =

2πr^2 + πr^2

These are like terms, just like adding 2x plus x.  So this simplifies to 3 π r^2
