Answer 1

Answer:

and answer 13 is in attachment...

Que14. (I) Let r1 and r2 be respectively the radii of apples and oranges

∵ 2r1: 2r2 = 2: 3

⇒ r1: r2 = 2: 3

4πr12: 4π22

2 = (r1/r2)2

= (2/3)2

= 4: 9

(ii) Let the height of the drum be h.

Volume of the drum = volume of the cylinder + volume of the sphere

π32h = (π32 × 8 + 4/3π33) cm3

⇒ h = (8 + 4)cm

⇒ h = 12vm
