Question

The height of a right circular cone is 7cm and radius of its base is 3 cm find its curved surface area, total surface area and volume ​

Answer 1

HEY MATE YOUR ANSWER IS HERE ^_^

l = √(r^2+ h^2)
= √(3^2+7^2)
= √(9 +49)
= √58

Total surface area =
$\pi \: r(l + r)$
22/7 × 3(√58 +3)
80.776

please make me a brainlist answer for the question
