Answer 1

Answer:

curved surface area of the cylinder is 176 sq cm

Step-by-step explanation:

height of the cylinder is 7 cm

diameter of the base is 8 cm

so, radius of the base is 8/2 cm=4 cm

curved surface area of the cylinder is

2 ×π×radius×height sq cm

=2×π×4×7 sq cm

=2×22×4×7/7 sq cm

=2×22×4 sq cm

=176sq cm
