The figure shows a big semicircle and two identical small semicircle inside a rectangle. The length of the rectangle is 53 cb and its breadth is 38 cm Find the perimeter of the shaded part give you answer correct to 2 decimal places

answer: was that a question or answer?

step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

40 minutes

step-by-step explanation:

add the time and multiply by 2
