Question

a vessel is in the form of a hemispherical bowl mountain by a hollow cylinder the diameter of hemisphere is 14 cm and the total height of the vessel is 13 cm find​

Answer 1

Explanation:

Diameter of hemispherical bowl is 14 cm

Radius = diameter/ 2 = 7 cm

Height of the vessel is 13 cm

Height of cylinder = Height of vessel - radius of hemisphere = 13-7 = 6cm

Total area of vessel : 2(\text{CSA of cylinder}+{\text{CSA of Hemisphere})

= 2(2\pi rh +2\pi r^2)2(2πrh+2πr

2

)

= 2\times 2 \pi \times r(h +r)2×2π×r(h+r)

= 2\times 2\times \frac{22}{7}\times7(7+6)2×2×

7

22

×7(7+6)

= 11341134

Thus the area of the vessel is 1134 square m.
