Step-by-step explanation:
hello jannat l
The answer would be B because I did this equation on a sheet of paper and I did the parentheses first which led me to my final answer B.
Answer:
D. 
Step-by-step explanation:
A circle measures 360 degrees and has an area 
The radius (also side length) is given:
.
The area of this circle is 
The area of a triangle is (1/2)bh, so this triangle is: 
Triangle area: A = 16 units^2.
- This is a right triangle that's also a 45, 45, 90 triangle. In these special triangles, the side lengths (AO and OB) will be the same. It also means the hypotenuse is such side length times the sqrt of 2.
Now, subtract the area of the triangle from 1/4 of the circle's area:
(1/4)32pi - 16 = 8pi - 16

Answer:
12.5663
Step-by-step explanation:
circumference = pi x diameter
d= 2r
d = (2)2
d=4
c=4pi
c=12.5663
