Question

Help would be much appreciated.
Please show all workings :)

Answer 1

See below

Explanation:

We know that

Volume of cylinder = πr²h

Given,

radius = h

height = 2m + 3

Now

Finding function

π(3)²(2m + 3)

π(9)(2m + 3)

π(18m + 27)

Thus,

V(m) = π(18m + 27)

Answer 2

9514 1404 393

Answer:

V(m) = (18m +27)π cm³

Explanation:

Substitute for h and r. It's really that simple.

V = πr²h

V = π(3²)(2m+3) = 9(2m+3)π

V = (9m+27)π . . . . cm³
