Question

Find the capacity of a cylindrical storage tank of height 2m and base diameter 1.4m

Answer 1

hi!
here's your answer .

here. . . . . . . . .
h(height) = 2m.

Diameter = 1.4m

$radius \: = \frac{1.4}{2} = 0.7m$
Radius (r) = 0.7m

Capacity of cylindrical tank =
$\pi {r}^{2} h$
$= \frac{22}{7} \times {0.7}^{2} \times 2$

$= \frac{22}{7} \times 0.49 \times 2$
$= 22 \times 0.7 \times 2$

$= 30.80 {cm}^{2}$

Thus
The Capacity of the cylindrical storage tank is 30.80 sq .cm.


hope this helps ! !!#

Answer 2

Answer:

3.08

Step-by-step explanation:

h=2m

d=1.4m

r=1.4/2 = 0.7

volume of a cylinder = 22/7 * r² * h

= 22/7 * 0.7² * 2

= 22/7 * 0.49 *2

= 22 * 0.07 * 2

= 44 * 0.07

= 3.08m²
