Answer:
D. inches.
Step-by-step explanation:
We have been given that the circle with center O has a minor arc BSA with a length of inches. The central angle is 40°.
To find the circumference of circle we will use formula:
, where
= measure of 360 degrees in radians and
= circumference of circle.
Let us convert measure of central angle into radians.
Upon substituting our given value in the formula we will get,
Cross multiplying we will get,
Hence, the radius of our circle is 27/4 inches.
Since the circumference of circle is . Upon substituting
we will get,
Therefore, circumference of our given circle will be inches and option D is the correct choice.
Answer:
C.) 7.14 in²
Step-by-step explanation:
The figure is made up of a square and a circle. The circle is divided in half and each piece is set on one side of the square. This means that the diameter of the circle is equal to the length of the sides of the square, 2 inches.
The area of the square can be found by multiplying length times the width:
The area of the square is 4 inches, and since we multiplied two lengths, we square the value:
A=4in²
Now find the area of the circle using the formula:
The radius is half of the diameter, so the radius is 1. Insert values and solve:
The area of the circle is equal to π. Add the values together:
The area of the figure is 7.14 in²
