Question

How many degrees is 1/9 of a semicircle?​

Answer 1

Answer:

20 degrees

Step-by-step explanation:

A semicircle is half of a circle.

1/9 of a semicircle is 1/18 of a circle.

1/18 of 360 = 20 degrees.

Answer 2

The degree of 1/9 of a semicircle is 20°.

What is a semi-circle?

A semicircle is half of a circle. It is a 2D shape formed when a circle is cut into two equal parts. We can create two semi-circles from any circle.

For the given situation,

The total angle of a circle is 360°

So, the total angle of the semicircle is 180°

Now, the degree 1/9 of a semicircle is given by

⇒ $(180)(\frac{1}{9} )$

⇒ $20$

Hence we can conclude that the degree of 1/9 of a semicircle is 20°.
