Answer:

Sorry mate, I can't write in Hindi, but I'll give the answer in simplest English possible.

Radius of hemisphere = 7/2 cm

Height of object (ठोस बेलनाकार) = 20 cm

Volume (आयतन) of cylinder = \tt{\pi r^{2} h}

= 22/7 × 7/2 × 7/2 × 20

= 770 cu. cm

Volume (आयतन) of 2 hemispheres = \tt{2 \times \frac{2}{3} \pi r^{3}}\\

= 4/3 × 22/7 × 7/2 × 7/2 × 7/2

= 179.67 cu. cm

Total volume = 770 + 179.67

= 949.67 cu cm
