Question

If the volume of a right circular cylinder, 7 cm high is 2200 cu.cm. What is the diameter of the base of cylinder?

Answer 1

Step-by-step explanation:

$volume = 2200cm {}^{3}$

we know that volume of right circular cylinder=

$\pi r {}^{2} h$

here

$\pi r {}^{2} h = 2200$

$\frac{22}{7} \times r {}^{2} \times 7 = 2200$

$r {}^{2} = \frac{2200 \times 7}{22 \times 7}$

$r {}^{2} = 100$

$r = 10cm$

it's my second answer....plz mark it as brainliest
