Answer:
c
d
Step-by-step explanation:
a)14pi
b)49pi
circumference of circle= 2pi r=2pi 7=14pi in
area of circle=pi r^2=pi(7)^2=49pi in^2
7/33 = 21 repeating and I'm pretty sure the question wants you to write it as an improper fraction. so your answer would be 40/33
x+x=90
2x=90 ,x=45 ,∆BAD=45
O_O UHMM I think B and C.. and A
b (1/15)
