Question

the volume of cylinder is 308 cm cube its height is 8 cm find its lateral surface area and total surface area
​

Answer 1

Step-by-step explanation:

• Volume of cylinder=308cm^2
• πr^2h=308
• 22/7×r^2×8=308
• r^2= 308×7/22×8
• r^2=12.25
• r=3.5cm

CSA of cylinder= 2πrh

• 2×22/7×3.5×8
• 176cm^2

TSA of cylinder= 2πr(r+h)

• 2×22/7×3.5(3.5+8)
• 253cm^2
