Question

Find the height of a solid right circular cylinder whose total surface area is equal to 314 cm and the
diameter of the base is 8 cm. (Use a = 3.14)​

Answer 1

Answer:

8.5cm

Step-by-step explanation:

TSA of right circular cylinder=314cm

Diameter=8cm

Radius=4cm

2πr(r+h)=314cm

2×3.14×4(4+h)=314

25.12(4+h)=314

4+h=314/25.12

4+h=314×100/2512

4+h=12.5

h=12.5-4

h=8.5cm

Hence,the height of the right circular cylinder is 8.5cm.
