30 the question last part

Answer 1

65$\pi$ cm²

Step-by-step explanation:

There seems to be a printing error in the last part of the question. Instead of $\pi$ they have mentioned h.

Volume = 2200/7cm³

Diameter = 10cm

Radius = 5cm

So, $\pi$r²h/3 = 2200/7

h = (2200*3*7)/(22*7*25) = 12cm

Lets compute the slant height s

s² = h² + r²

s² = 144 + 25 = 169

s = 13 cm

Curved Surface Area = $\pi$rs = $\pi$ * 5 * 13 = 65$\pi$ cm²
