#### Transcript of Perimeter of a Heart

STEP ONE
3+3=6
STEP THREE
STEP TWO
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.
STEP FOUR
Now, we add up the perimeter of the circle and the triangle.
Perimeter of a
HEART
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.
3cm
3cm
c=dxπ
c=6x3.14
c=18.84cm
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.

S3
p=s1x2+s3
p=8x2+7
p=16+7
p=23cm
S1=8cm
S3=7cm
CIRCUMFERENCE: 18.84cm
TRIANGLE PERIMETER: 23cm

+ 23
19.07
(Overall, the perimeter of the heart 19.07cm.)
