The radius and height of a solid cylinder is 8 cm and 14 cm respectively. Find, correct to two d.p the total surface area.
(Take π=227)
1,106.29cm2
1,016.29cm2
1,106.89cm2
1,206.27cm2
Correct answer is A
radius = 8cm , height = 14cm and π=227
total surface area of a solid cylinder = 2πrh+2πr^2 = 2πr( h + r )
2 \times \frac{22}{7} \times 8( 8 + 14)
2 \times \frac{22}{7} \times 8 \times 22
\frac{7744}{7}
= 1,106.29cm^2
