Question

the curved Serface
area of a cylinder is
4400 cm² and the circumference of its base
is
22oum
find the height of the cylinder​

Answer 1

Step-by-step explanation:

we know that the circumference of a circle is

$2\pi \: r$

so

$2\pi \: r \: = 22 \\ 2 \times \binom{22}{7} \times r = 22 \\ 2 \times r = \binom{22 \times 7}{22} \\ r = 14cm$

then radius is 14 cm

now the curved surface area of the cylinder is

$2\pi \: rh \: \\ 2 \times \binom{22}{7} \times 14 \times h = 4400cm \\ so \: we \: get \: \binom{4400}{88} = 50$
