A cylinder cop has a circular base of radius 7cm & height of 10cm taking 22/7(a)calculate it curved surface(b)d area of it circular base
that's cylindrical cup sheesh.
the area of the circular base, is just the area of a circle.
pi r^2
the curved surface is just the circumference times the height:
2pi r h
Now just plug in your values for r and h
Good
A cylindrical cup as a circular base of radius 7 cm and height of 10 cm take pie as 22/7 calculate the curved surface area and the area of the circular base

To calculate the curved surface area of a cylinder, you use the formula:
Curved Surface Area = 2 * π * radius * height
In this case, the radius is given as 7cm, and the height is given as 10cm. Substituting these values into the formula, we get:
Curved Surface Area = 2 * (22/7) * 7 * 10
Simplifying, we have:
Curved Surface Area = (44/7) * 7 * 10
The radius cancels out, and we have:
Curved Surface Area = 44 * 10
Curved Surface Area = 440 square cm
To calculate the area of the circular base of the cylinder, you use the formula:
Area of the Circular Base = π * radius^2
In this case, the radius is given as 7cm. Substituting this value into the formula, we get:
Area of the Circular Base = (22/7) * 7^2
Simplifying, we have:
Area of the Circular Base = (22/7) * 49
Area of the Circular Base = 154 square cm
