Question

Find the total Surface of a hernisphere of radius
10 cm (useπ= 3.14)​

Answer 1

$\bf\fbox\red{Given}$$\longrightarrow$

Radius=10cm

Name of the shape=hemisphere

π=3.14

$\bf\fbox\orange{To Find}$$\longrightarrow$

Total Surface Area of hemisphere

$\bf\fbox\pink{Solution}$$\longrightarrow$

T.S.A =3πr²

=3×3.14×10

=3×31.4

=94.2cm²
