Question

Find
total surface area of the cylinder if the radius is 5cm and height is 40cm

Answer 1

tsa=2πr(h+r)

so

t.s.a=2×3.14(40+5)

=90×3.14

=282.60cm

Answer 2

Radius =5cm
Height =40cm

Let Total Surface Area be TSA ---

$TSA\: of \: cylinder \: = 2\pi \times r(h + r)$

Assuming pi to be ---

$\frac{22}{7}$

$TSA = 2 \times \frac{22}{7} \times 5 \times (40 + 5)$

$TSA = 1414.285$

Rounding of, the Total Surface Area of the cylinder is ---

$1414.28 {cm}^{2} \:$
