Question

Radius of circular surface of the cup r1 66, r2 44 , height of the cup ( h) 24 cm . to find volume of the cup

Answer 1

Answer:

231120.69cm³ approx. (pls. check the values)

Explanation:

$\frac{\pi }{3} h (r_{1}^{2}  +r_{2} ^{2} + r_{1} r_{2} )$

$8\pi (66^{2} +44^{2} +44×66)$

$8\pi  (4356+1936+2904)$

$8×\frac{22}{7}× 9196$

231120.69cm³ approx.
