A vitamin capsule is roughly a cylinder of length 2.2 cm with a hemisphere on each end, radius 1.4 cm. (i) Total length is 5 cm here. Its total surface area, to estimate its coating, equals 2*π*r*h + 4*π*r^2. Compute it in cm^2. (Take π = 22/7)

Question

Accepted Answer

44. 2*π*r*h = 2*(22/7)*1.4*2.2 = 2*22*0.2*2.2 = 19.36. 4*π*r^2 = 4*(22/7)*1.96 = 4*22*0.28 = 24.64. Total = 19.36+24.64 = 44 cm^2.

A vitamin capsule is roughly a cylinder of length 2.2 cm with a hemisphere on each end, radius 1.4 cm. (i) Total length is 5 cm here. Its total surface area, to estimate its coating, equals 2π $r * h + 4$ π $r^{2}$ . Compute it in $cm^{2}$ . (Take π = $\frac{22}{7}$ )
