Answer:
VOLUME OF CYLINDER = PI R² H
IF AREA OF BASE = 22CM² THEN
R = 3.5CM
VOLUME = 22/7 × 3.5 × 3.5 × 10
= 385 CM³

Answer:
220 cm³
Step-by-step explanation:
Volume = πr²h
area = πr²
Therefore
Volume = area × height
= 22 × 10
= 220 cm³
Note : In the answer given above , the person used perimeter formula instead of area to find the radius of the base.
If we apply the formula here we will get the radius as √7 cm
Area = πr²
22 = 22/7× r²
7 = r² (22 and 22 will be cancelled)
√7 = r
Then if you do by substituting r
V = (22/7)×√7×√7×10
= (22/7)×7×10
= 22×10(7 and 7 will be cancelled )
= 220 cm³
