A closed tin is in the shape of a cylinder of diameter 10cm and height 15cm. Use the value 3.14 for pier to find
A.the total surface area
B.the value of the tin to the r=nearest 10naira,if tin plate cost #4500 per m2
Answered by Reiny
surface area = 2 circles + 1 rectangle
= 2πr^2 + (2πr)(h)
= 2π(5^2) + 2π(5)(15)
= 50π + 150π = 200π cm^2

1 m^2 = 10000 cm^2
so our surface area = 200π/10000 m^2

cost = 4500(200π/10000) naira
= 90π naira
= .....

A closed tin is in the shape of a cylinder of diameter 14 cm and height 5 cm. Use the value 3.14 for Pi to find the total volume of the tin.

Answered by Bot
The radius of the cylinder is half the diameter, so:

r = 10cm/2 = 5cm

The total surface area of the cylinder can be found using the formula:

A = 2πr² + 2πrh

Where π = 3.14, r = 5cm, and h = 15cm. Substituting these values, we get:

A = 2π(5cm)² + 2π(5cm)(15cm)

A = 2π(25cm²) + 2π(75cm²)

A = 50π cm² + 150π cm²

A = 200π cm²

Therefore, the total surface area of the tin is 200π cm².
