Question

the volume of a right circular cylinder is 2310cm3. if the radius of its base is 7cm then its height is mcq
​

Answer 1

r=7cm, h=15cm

Volume of a cylinder =πr²h= 22/7 ×7cm ×7cm×15cm=2310cm³

Answer 2

Question:-

⌬ The volume of a right circular cylinder is 2310 cm³. If the radius of its base is 7 cm, then its height is

⠀

Given:-

• Volume of a right circular cylinder is 2310 cm³.
• Radius of its base is 7 cm.

⠀

To find:-

• Height of circular cylinder.

⠀

Solution:-

★ Using Formula

$\star{\boxed{\sf{\orange{Volume~ of~ a~ Cylinder = \pi r^2h}}}}$

⠀

$\large{\tt{\longmapsto{\pi r^2h = 2310}}}$

⠀

$\large{\tt{\longmapsto{\dfrac{22}{7}\times 49\times h = 2310}}}$

⠀

$\large{\tt{\longmapsto{h =\dfrac{2310}{22\times 7}}}}$

⠀

$\large{\tt{\longmapsto{h =\dfrac{330}{22}}}}$

⠀

$\boxed{\large{\tt{\longmapsto{\red{h = 15~ units}}}}}$

⠀

※ Hence, height of circular cylinder is 15 units.
