Perimeter of a Heart
Transcript of Perimeter of a Heart
Thank you for your attention!
Take the two semi-circles from the heart and find the diameter of each.
Once done, use the circumference formula "c=dxπ". We use this formula because if you put the two semi-circles together you get a circle.
Now, we add up the perimeter of the circle and the triangle.
Perimeter of a
Here is a normal heart.
Each heart has one circle and one isosceles triangle.
Draw a line here.
Two semi-circles and an isosceles triangle are now visible.
Also, you need to double the length of the diameter on each semi-circle. So say that both the diameters were 3cm in length. You'd add 3 with itself and the answer you get is what you have to multiply with pi.
At the bottom of the circle, there is an isosceles triangle. We use the formula "p=s1x2+s3" because an isosceles triangle is a triangle with two equal sides and if you multiply s1 by 2, you get the answer for the length of both equal sides. And s3 is the side that is not equal to the other two sides.
TRIANGLE PERIMETER: 23cm
(Overall, the perimeter of the heart 19.07cm.)
