Question

The sum of circumfrence of a circle and perimeter of rectangle is 168cm and ratio of raidius of the circle and breadth of the rectangle is 19:2. Find the area of another circle whose raidius is 28% of the diagonal of the rectangle​

Answer 1

Step-by-step explanation:

the area of the rectangle is 168cm². if the ratio of the radius of the circle to the breadth of the rectangle is 19:2, find the radius of the circle

Answer 2

Answer:

let the radius of circle be 19x and breadth of rect be 2x.

perimeter of rect=2 (l+b),circumference of circle =2×22/7×19x

168=2 (l+2x)+44/7×19x

84=l+2x+22/7×19x

Now solve for x
