5. The circumference of a base of acylinder is 176 cm and its height is 60 cm, find the volume of the cylinder.
Answers
Answer:
R = 176×7/44 => 28 cm
Height of cylinder = 65 cm
Therefore,
Volume of cylinder = πR²H => 22/7 × 28 × 28 × 65
=> 22 × 4 × 28× 65
=> 160160 cm².
TSA of cylinder = 2πR(R+H)
=> 2 × 22/7 × 28 ( 28 + 65)
=> 44 × 4 × 93
=> 16368 cm².

Answer:
volume= 147840 cm³
Step-by-step explanation:
Circumference= 2 * pi * r. [r stands for radius]
176= 2*pi*r
r=176/(2*pi) [ we take pi as 22/7 for easy cancellation]
r=28 cm. ( i am not showing the calculation part. you can easily get this by taking pi as 22/7)
area of base of cylinder= pi*r*r= (22/7)*28*28=2464 cm²
volume of a cylinder=area of base* height= 2464*60=147840 cm³
