the area of circular base of a cone is 616 cm² and its slant height is 20.5 cm find the curved surface area and the total surface area of the cone

The curved surface area is 902 cm^2

The total surface area is 1,518 cm^2

Step-by-step explanation:

We can get the radius from the area of the circular base

The area of the circular base is;

A = pi * r^2

616 = pi * r^2

r^2 = 196.078

r= √196.078

r = 14 cm

The curved surface area is;

pi * r * l

= 22/7 * 14 * 20.5

A = 902 cm^2

The total surface area is the sum of the curved surface area and the area of the circular base

That will be;

902 + 616 = 1,518 cm^2

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
