Question

find the volume of a right circular cylinder if radius of its base=7cm and height=1.5dm

Answer 1

Answer :-

Volume of a right circular cylinder is 231 cm³

Solution :-

Given

Radius of right circular cylinder(r) = 7 cm

Height of the right circular cylinder (h) = 1.5 m

We know that

Volume of a right curcular cylinder = πr²h

= 22/7 * 7² * 1.5

= 22/7 * 49 * 1.5

= 22 * 7 * 1.5

= 231 cm³

Therefore volume of a right circular cylinder is 231 cm³

Additional Information :-

• Total surface area of a right circular cylinder = 2πr(r + h)

• Lateral surface area of a right circular cylinder = 2πrh

$\huge{\mathfrak{</p><p><strong>Answer:</strong></p><p>}}$

$\large{\bf{Radius \:of \:cylinder(R)= 7 cm }}$

$\large{\sf{Height \:of \:cylinder = 1.5 cm}}$

$\huge{\bf{Volume \:=\:π × r × r × h}}$

$\large{\sf{22/7 × 7 × 7 × 1.5}}$

$\large{\sf{22 × 7 × 15/10}}$

$\large{\sf{2310/10 }}$

$\large{\sf{231 cm3}}$
