Question

find the surface area and volume of a circular cone​

Answer 1

Step-by-step explanation:

Volume of a cone: V = (1/3)πr2h.

Slant height of a cone: s = √(r2 + h2)

Lateral surface area of a cone: L = πrs = πr√(r2 + h2)

Base surface area of a cone (a circle): B = πr. ...

Total surface area of a cone: A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

Answer 2

Answer:

You mean the formulae?

CSA of a cone=πrl

TSA of a cone=πr(l+r)

Volume of a cone=1/3πr^2h
