The circumference of the edge of a hemispherical bowl is 132cm. Find the capacity of the bowl (use ⫪=22/7)

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

As given , Circumference = 132cm

(The meaning of capacity is volume)

As we know the formula for circumference

$2\pi \times r$

${\bold{\purple{⟼}}}$2πr = 132

${\bold{\pink{⟼}}}$πr = 66

${\bold{\red{⟼}}}$(22/7) × r = 66

${\bold{\green{⟼}}}$(11/7) × r = 33

${\bold{\orange{⟼}}}$r = 33 × (7/11)

${\bold{\blue{⟼}}}$r = 3×7

${\bold{\purple{⟼}}}$r = 21

As we know that

$v = \frac{2}{3} \pi{r}^{3}$

${\bold{\pink{⟼}}}$V = (2/3)π(21³)

${\bold{\red{⟼}}}$V = (2/3)π (21×21×21)

${\bold{\green{⟼}}}$V = 2π(7×21×21)

${\bold{\orange{⟼}}}$V = 2 ×(22/7)(7×21×21)

${\bold{\blue{⟼}}}$V = 2 × (22)(21×21)

$\underline{\overline{\mid{\bold{\purple{V = 19404cm³}}\mid}}}$

Answer 2

Step-by-step explanation:

RADIUS OF SEMICIRCLE IS 21cm ...

so,

by finding value of capacity...by the formula stated in the above pic...we get VOLUME=19404cm^3 ....
