Best Answer

If the semicircle is placed on 1 side of the rectangle:

  1. Find the total perimeter(circumference) of the side opposite to the one with the semicircle's base and the 2 sides perpendicular to the semicircle's base.
  2. The formula for circumference of a circle is 2πr.Thus for the semicircle we will take the circumference as πr.
  3. Find the sum of 1st and 2nd points. This is the final answer.

How do we find a perimeter of a semicircle?

It is its diameter plus half of its circumference


How do you find the circumference of a semicicle?

circumference of a semicircle = pi * diameter / 2 (pi multiplied by the diameter and divided by 2)


How do you find the distance around a semicircle?

It is half the circle's circumference plus its diameter.


How do you figure the perimeter of a semicircle if the the straight side is 36?

Consider the straight side as the diameter of a circle, find the circumference of the circle, calculate half the circumference and then add it to the diameter. circumference = pi x diameter = 3.14 x 36 = 113.04 perimeter of semicircle = 1/2 circumference + 36 = 56.52 + 36 = 92.52


How do you find the perimeter of a semicircle?

The circumference of a semicircle is pi times the radius plus the diameter.


How to find the length of the curved part of the semicircle?

A circle is two semicircles put together. The circumference of a circle is the length around it, so half of that would be what you are aiming for. Let's call the circumference "c" and the radius (the straight part of the semicircle) "r". Pi is also needed in this problem, so we can use "π". The equation for the circumference of a circle is c=2πr. Replace "r" with the length of the straight part of the circle, and do the math. Divide your answer by 2.Example:r=2c=2πrc=2π2c=4πc=(approximately)12.5712.57 divided by 2 equals approximately 6.29.The length of the curved part of the semicircle is 6.29!Hope this helps!


If diameter is 7 find perimeter of semi circle?

Pi times the diameter gives you the circumference. Then divide that answer by two. Then add in the diameter - and, voila, you have your answer as to the perimeter of a semicircle.


How do you find the diameter of a semicircle when radius is given?

The diameter of the semicircle will be twice the radius.


How do you find the radius of a semicircle?

it is have the diameter


How do you find the perimeter of a shape that has a semicircle?

To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.


How do you find the circumference of a half circle if you have the diameter?

The length of the curved part of the semicicle is π*d/2 where π is the transcendental number approximated by 3.14159 and d is the diameter. The length of the straight part of the semicircle is, of course, d.


Find the perimeter of a semicircle of diameter 10cm?

First find the circumference of the whole circle using Pi x diameter. Halve the answer and add the diameter. Thus: 3.1416 × 10 = 31.416 ÷ 2 + 10 = 25.708cm So the perimeter of the semi-circle is 25.7cm
