The equation to find the curved surface area of a cone is A=πHr, where r denotes the radius of the base of the cone, and H denotes the slant height of the cone.

In this case, we know A (594), r (7) and π (a constant = 3.1415...).

Our only unknown is H.

We therefore rearrange the equation to make H the subject. This will give H=A÷(πr).

Plug in the numbers to get H=594÷(π×7) and you end up with H=... more
