Question

A=πr^2+2πrh

Answer 1

Um, what are we supposed to do with this?

Answer 2

sorry forgot to say, how do ( make π the subject?

Answer 3

Solve for \(\pi\)?

Answer 4

make π the subject ie π= what in terms of A, r and h? sorry im not being v clear here

Answer 5

yes

Answer 6

So you are trying to "solve for pi". First combine like terms:
A = pi*r^2 + 2*pi*r*h = (r^2 + 2*r*h)*pi

Now divide the coefficient off of pi:
A/(r^2 + 2*r*h) = pi

And there's your answer.

Answer 7

make \(\bf \large \pi\) the "subject" just means "solve for \(\bf \pi\) or "isolate" \(\bf \pi\)

Answer 8

Thank you so much :), sorry didn't understand 'mathsy' terms x

Answer 9

I'm guessing that is the formula for cylinder area.

Answer 10

then you're guessing right :)

Answer 11

thanks :-)
