Question

The radius and height of a Cone are 7cm and 24cm respectively, then its slant height (L) is?​

Answer 1

$\huge\red{\mid{\fbox{\tt{Answer}}\mid}}$

A=πrl. Hence, the curved surface area of the cone with a radius of 7 cm and slant height of 10 cm respectively is 220 sq. cm. Note: In any cone with radius r and height h, the slant height h is given by l=√r2+h2

Answer 2

Answer:

A=πrl. Hence, the curved surface area of the cone with a radius of 7 cm and slant height of 10 cm respectively is 220 sq. cm. Note: In any cone with radius r and height h, the slant height h is given by l=√r2+h2
