★FIND:
the surface area of solid cylinder of radius 2.0 cm and height 10.0cm is equal to______ (mm)^2
★GIVEN,
(1cm=10mm)
Radius, r = 2.0 cm ➡️2×10➡️ 20 mm
Height, h = 10.0 cm ➡️10×10➡️100 mm
★SOLUTION:
Total surface area of a cylinder=2πr(r+h) ➡️2πr (r + h)
➡️(2)(3.14)(20)(20+100)
➡️125.6(120)
➡️15,072mm^2
➡️1.5072×10^4mm^2
The surface area of a solid cylinder of radius 2.0 cm and height 10.0 cm is equal to 1.5072×10^4 mm2
