For the lateral surface area, you'll have the formula:

A = π r

*l*

where A is the area

*r is the radius*

*l*is the slant height

A = π (3cm)(7cm)

A = 21 π cm²

__A = 65.97 cm²__

For the total surface area, you'll have:

A = π r

*l*+ π r²

A = π(3cm)(7cm) + π(3cm)²

A = 30 π cm²

__A = 94.25 cm²__
