Answer:

16 degrees

Step-by-step explanation:

This is a right triangle with shorter leg 3 in and hypotenuse 11 in. The 3 in side is opposite the angle theta. Thus, by definition of the sine function,

sin theta = 3/11 = 0.273

Using a calculator and the inverse sine function, we get theta = 0.276 radian, or 15.8 degrees. This rounds up to 16 degrees.

Hello!

First you have to find the length of the side under the quarter circle

20 - 11 = 9
------------------------------------------------------------------------------------------------------
Next you have to find the circumference of the quarter circle

You use the equation to find the circumference of a circle and divide the answer by 4

The equation is $2 \pi r$

r is radius

Put in 3.14 for pi and the numbers you know

2 * 3.14 * 11 = 69.08

Divide this by 4

69.08 / 4 = 17.27
-----------------------------------------------------------------------------------------------------
Finally you add all the values you know

20 + 2 + 17.27 + 9 + 11 + 2 = 61.27cm
------------------------------------------------------------------------------------------------------
The answer is 61.27cm

Hope this helps!
