Question

I need the solution.The answer is 179.67​

Answer 1

Answer:

179.67 cm^2

Step-by-step explanation:

Height of cup=10.5cm

Hemisphere: r=3.5cm

Cone: r=3.5cm and h=10.5 - 3.5=7cm

Volume of ice cream in conical cup= volume of hemisphere + volume of cone

= 2/3πr^3 + 1/3πr^2h

= πr^2(2/3r +1/3h)

= 22/7 x 3.5 x 3.5 (2/3x3.5 + 1/3 x 7)

= 22x0.5x3.5 [1/3(2x3.5 + 7)]

= 38.5 [1/3(7+7)]

= 38.5 [1/3 x 14]

= 38.5 x 14/3

= 539/3

= 179.666

= 179.67cm^2(approx.)
