Question

Find the total surface area of a hemisphere of radius 10cm. ( use π=3.14)
​

Answer 1

Step-by-step explanation:

total surface area of hemisphere 3 a^2

3(10)^2=3(100)

300m^2

Answer 2

Answer:

$\huge\underline{\overline{\mid {\bold {\green{AnsWer}}\mid}}}$

$radius \: = 10cm$

$surface \: \: \: area \: \: \: of \: \: \: hemispere = 3\pi {r}^{2}$

$= > 3 \times \frac{22}{7} \times ({10}^{2} )$

$= > 3 \times \frac{22}{7} \times 100$

$= > \frac{66}{7} \times 100$

$= > \frac{6600}{7}$

$= > 942.857 \: cm$
