Answer:

395.841 m²

Explanation:

surface area = 2πrh + 2πr² and r = 7 m radius

h = 2 m

Plugin

2π (7) 2 + 2π (7)²

multiply into itself than add

87.965 + 307.867

add

395.841 m²

Answer:

Explanation:

surface area = 2πrh + 2πr²

where r = 7 m radius

h = 2 m

plugin values into the formula

surface area = 2πrh + 2πr²

= 2π (7) 2 + 2π (7)²

= 87.965 + 307.867

= 395.841 m²
