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
Therefore your answer would be 395.841 m²
surface area = 2πrh + 2πr²
where r = 7 m radius
plugin values into the formula
= 2π (7) 2 + 2π (7)²
= 87.965 + 307.867
= 395.841 m²
