Answer:

A = 244.92 cm² or 78π

Step-by-step explanation:

A = πrl

r = 6 cm

l = 13 cm

π ≈ 3.14 cm

A = 3.14 × 6 × 13

A = 3.14 × 78

A = 244.92 cm²

Answer:

Step-by-step explanation:

A= 3.142 x r x l

r=6

l=13

total surface area = area of the curved section + area of the base

area of curved section = 6x13=78pi

aeea of base= 6x6=36pi

78+36=114pi = 358.1cm squared
