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
= .....
I will let you do the arithmetic

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.
It is correct
A close tin is the shape of a cylinder of diameter10cm and height15cm,use the value3.14for ^to find the total surface area of the in
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.
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.
