Question

Find the curved surface area of a cone if its diameter is 8

cm and slant height is 28cm.​

Answer 1

Answer:

Here it is.........

CSA of cone = pi rl

>> 22/7× 4×28 = 352 cm^2

Answer 2

Diameter=8cm

Radius=8cm/2=4cm

Slant Height=28cm

Curved surface area of cone =πrl

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{22}{7} \times 4 \times 28 = 352cm ^{2}$
