Most Upvoted Answer
From a circular sheet of a radius 4cm and a circle of a radius 3 cm is...
Given data:
- Radius of the circular sheet = 4 cm
- Radius of the circle removed = 3 cm
Calculating the area of the circular sheet:
The area of a circle is given by the formula A = πr^2, where A is the area and r is the radius.
So, the area of the circular sheet is A_sheet = π(4)^2 = 16π cm^2.
Calculating the area of the circle removed:
The area of the circle removed is A_removed = π(3)^2 = 9π cm^2.
Calculating the area of the remaining sheet:
The remaining sheet is the circular sheet minus the circle removed. So, the area of the remaining sheet is A_remaining = A_sheet - A_removed.
Simplifying the expression:
A_remaining = 16π - 9π = 7π cm^2.
Therefore, the area of the remaining sheet is 7π cm^2 or approximately 21.98 cm^2.
Summary:
- The area of the circular sheet with a radius of 4 cm is 16π cm^2.
- The area of the circle removed with a radius of 3 cm is 9π cm^2.
- The area of the remaining sheet is the difference between the area of the circular sheet and the area of the circle removed, which is 7π cm^2 or approximately 21.98 cm^2.
- Radius of the circular sheet = 4 cm
- Radius of the circle removed = 3 cm
