Question

The circumference of a circular base of a cylinder is 44 cm and its height is 15 cm. The volume of the cylinder is

a) 1155 cu. cm
b) 2310 cu.cm
c) 770 cu.cm
d) 1540 cu.cm

Please give me the answer fast.

Answer 1

Answer:

2310 cu.cm

Step-by-step explanation:

circumference = 2×(22/7)×r

r= (44×7)/(2×22)

r= 7 cm

volume = (22/7) × r²×h

= (22/7) × 7×7 × 15

= 2310

Answer 2

Given :-

• Circumference of Base = 44cm
• Height of Cylinder = 15cm

To Find :-

• Volume of Cylinder

Solution :-

➞ Circumference = 2πr

➞ 44 = 2 × 22/7 × radius

➞ 44 / 2 = 22/7 × radius

➞ 22 = 22/7 × radius

➞ 22 × 7 / 22 = radius

➞ 154 / 22 = radius

➞ 7 cm = radius

________________

⟾ Volume of Cylinder = πr²h

⟾ Volume of Cylinder = 22/7 × (7)² × 15

⟾ Volume of Cylinder = 22/7 × 7 × 7 × 15

⟾ Volume of Cylinder = 22 × 7 × 15

⟾ Volume of Cylinder = 154 × 15

⟾ Volume of Cylinder = 2310cm³

Thus Volume of Cylinder is 2310cm³
