MCQ
What is the total surface area of a solid hemisphere of diameter 'd'?
- A$3 \pi d^2$
- B$2 \pi d^2$
- C$\frac{1}{2} \pi d^2$
- ✓$\frac{3}{4} \pi d^2$
✓
Answer
Correct option: D.
$\frac{3}{4} \pi d^2$
(d)
Total surface area of a solid hemisphere of radius r is $S=3 \pi r^2=3 \pi\left(\frac{d}{2}\right)^2=\frac{3}{4} \pi d^2$
Total surface area of a solid hemisphere of radius r is $S=3 \pi r^2=3 \pi\left(\frac{d}{2}\right)^2=\frac{3}{4} \pi d^2$
