Question

Find the volume curved surface area and total surface area of a right circular cone whose are radius is 7 cm and height 24 cm.PLZ ANSWER​

Answer 1

Answer:

550 cm²

Step-by-step explanation:

Given, Radius of cone , r = 7 cm , and Height , h = 24 cm.

We know , l² = r² + h²

=) l² = 7² + 24²

=) l² = 49 + 576

=) l² = 625

=) l² = √625 = 25 cm

=) l = 25 cm

Therefore the curved surface area of cone is = πrl

= 22/7 x 7 x 25

= 22 x 25

= 550 cm²

Hence the curved surface of cone is 550 cm²
