Question

is the circumference of the circle is half of perimeter of a rectangle having area of 7600 square with length 100cm find the radius of the circle​

Answer 1

Answer:

Area of rectangle = 7600

Length of rectangle = 100

Breadth = Area / length

= 7600 / 100

= 76

Perimeter of rectangle = 2 ( l + b)

= 2 ( 100 + 76)

= 2 ( 176)

= 352

Circumference of circle = 1 / 2 perimeter of rectangle

$2\pi \: r = \frac{1}{2} \times 352$

$2\pi \: r = 176$

$2r = 176 \times \frac{7}{22}$

$2r \: = 56$

$r = \frac{56}{2}$

$r \: = 28$

Ans) the value of r is 28unit.

Answer 2

Answer:

Area of rectangle = 7600

Length of rectangle = 100

Breadth = Area / length

= 7600 / 100

= 76

Perimeter of rectangle = 2 ( l + b)

= 2 ( 100 + 76)

= 2 ( 176)

= 352

Circumference of circle = 1 / 2 perimeter of the rectangle

Explanation:

Ans) the value of r is 28unit.
