Question

the outer and inner diameter of a hemispherical bowl are 17cm and 15cm.find the cost of polishing it over at 25 paisa
$|$
tsa of hemisphere$= 3πr²
$3\pir \times {r}^{3}$
​

Answer 1

Answer:

The outer diameter =162129/28

after division=0.000172701984

The inner diameter=111375/28

after division=3977.67857

Step-by-step explanation:

first find the value of outer radius(r) by dia.

then,put value in the formula and multiply then divide

then find the value of inner r by dia.

then,put the value in the formula and multiply then divide
