Answer: =60π cm2

Step-by-step explanation:

Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, h is the height= 7cm and r is radius= 3cm

Slot the values into the formula:

2π(3 × 7 ) + 2π (3)^2

2 π 21 + 2π9.....multiply 2 by 21, and 2 by 9

42π + 18π

=60π cm2

I hope this helps.
