Answer 2

Answer:

Radius = 70 cm

Lateral Surface Area = 2200 cm²

Step-by-step explanation:

Find the radius:

Circumference = 2πr

2πr = 440 cm

r = 440 ÷ 2 π

r = 70 cm

Find the lateral surface area:

Lateral Surface Area = 2πrh

Lateral surface area = 440 x 5 = 2200 cm²

Answer: The radius is 70 cm and the lateral surface area is 2200 cm²
