It would be C.
HOPE THIS HELPS!!! PLEASE MARK BRAINLIEST!!!
Answer:
Step-by-step explanation:
(3-
)(3+)
=(3)^2-( )^2
=9-2
=7
14. the length of the arc is found by using the formula 2*PI*r*angle/360
the circle has a radius of 2 and the known angle is 90 degrees
so you now have: 2 * pi * 2 * 90/360, since the answer needs to be in terms of PI, remove pi from the equation for now:
2*2 *90/*360 = 1
the arc length = 1PI, or just PI
16. the area of the parallelogram is L x W : 9 *6 = 54
the area of the circle is: PI *r^2 = pi * 3^2 = 28.26
area of shaded region is subtracting the area of the circle from the parallelogram: 54 - 28.26 = 25.74 square inches
Perimiter is distance around
paralallogram has 4 sides, 2 pairs of paralell sdes
in a paralellogram, the paralell sides are equal legnth
so
perimiter=7+7+11+11=36
answer is 36 inches
