How many circles, each with a 4 inch radius, can be cut from a rectangular sheet of paper, measuring 16 inches x 24 inches?
Answers
Answer:
answer will be 11.2 means 11 or 12
Step-by-step explanation:
since in this question we have given the area from which we have find the number of circle.
area of rectangle=. w*l =16*24=384
- area of circle=pi r2 = 3.14*16=34.24
- so finally,384/34.24=11.2
Answer:
7 circles having a radius of 4 inches can be cut from the given sheet of paper.
Step-by-step explanation:
Given:
Radius of circle (r) = 4 inches
Length of rectangle (l) = 24 inches
Breadth of rectangle (b) = 16 inches
To find:
Number of circles
Formula:
Number of circles = A(rectangle) / A(circle)
Step 1:
The dimensions of the rectangular sheet of paper are 16 × 24 sq. inches
Therefore, the area of the sheet of paper is
A(rectangle) = l × b
A(rectangle) = 16 × 24
A(rectangle) = 384 sq. inches
Step 2:
The radius of the circle is 4 inches. So, the area of the circle is
A(circle) = π × r ×r
A(circle) = 3.14 × 4 × 4
A(circle) = 50.24 sq. inches
Step 3:
Number of circles = A(rectangle) / A(circle)
Number of circles = 384/50.24
Number of circles = 7.6
Therefore, a total of 7 circles can be cut.
