Question

volume of a cylinder is 6237cm3. find the radius if it's height is 4.5cm

Answer 1

radius is 21 cm for above question

Answer 2

Hey mate .
========

Given,

Height of the cylinder , h = 4.5 cm

Radius of the cylinder , r = ?

we know,

Volume of a cylinder =$\pi(r) {}^{2} h \\ \\ = > 6237 = \frac{22}{7} \times r {}^{2} \times 4.5 \\ \\ = > 6237 \times \frac{7}{99} = r {}^{2} \\ \\ = > 441 = r {}^{2} \\ \\ = > \sqrt{441} = r \\ \\ = > 21 = r$

Thus, Required radius of the cylinder = 21 cm

Hope it helps !!
