Question

If the radius of a solid hemisphere is 5cm, then find its curved surface area and total surface area. (π = 3.14)​

Answer 1

Answer:

Step-by-step explanation:

Curved surface area = 2πr^2 = 2 x 3.14 x 25 = 157 cm^2.

Total surface area = 3πr^2 = 3 x 3.14 x 25 = 235.5 cm^2.

Answer 2

Answer:

Step-by-step explanation:

Radius of hemisphere= 5cm

CSA of hemisphere=2πr^2= 2×3.14×5×5= 10×3.14×5= 31.4×5= 157cm^2

TSA of hemisphere= 3πr^2= 3×3.14×5×5= 3×3.14×25= 3.14×75= 235.5cm^2
