Answer:
(A) 3πr²
Step-by-step explanation:
Find the curved surface area of the hemisphere:
Curved Surface area of a sphere = 4πr²
Curved surface area of a hemisphere = 4πr² ÷ 2 = 2πr²
Find the area of the circle:
Since hemisphere has a circle exposed after slicing into half.
Area of circle = πr²
Find the total surface area of the hemisphere:
Therefore total surface area of a hemisphere = 2πr² + πr² = 3πr²
