Question

I HAVE A SEMICIRCLE WITH A DIAMETER 16cm. How do I find the perimeter of the SEMICIRCLE

Answer 1

Perimeter is 41.1327 centimeters

Explanation:

The perimeter of a semi-circle is the circumference of the full circle plus the length of the diameter.

To find the circumference of a circle, just multiply the diameter by pi:

`c=\pi* d\\c=\pi* 16\\c=50.2655`

Now, add the diameter to half of it:

`p=(c)/(2)+d\\p=(50.2655)/(2)+16\\p=25.1327+16\\p=41.1327`

Answer 2

Perimeter of Semicircle

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.21-Oct-202
