Question

The volume of a cylinder having 7 cm radius and 5 cm height is ___________ A. 550 cm³. B. 660 cm³. C. 770 cm³. D. 880 cm³

Answer 1

Answer:

C) The volume of a cylinder having 7 cm radius and 5 cm height is 770 cm³.

Step-by-step explanation:

Given:

Radius (r) = 7 cm

Height (h) = 5 cm

Find: The volume of a cylinder

Formula: The volume of a cylinder    $=\pi r^2h$

The volume of a cylinder

$= \frac{22}{7} \times (7)^2 \times 5\\=\frac{22}{7} \times7\times7 \times 5\\= 22 \times 7 \times 5\\\\= 770 cm^3$

So, The volume of a cylinder 770 cm³.
