Answer:
a. 254.34, b. 56.52
Step-by-step explanation:
a. A = πr^2,
A = 3.14(9^2)
A = 3.14*81
A = 254.34
b. C = πd
C = 18*3.14
C = 56.52
11/5−7/4+2/1
=49/20(Decimal: 2.45)
-9.87
-4.53 -5.43
= -9.87
B
cause on T4L you have to round it to the nearest whole and I put B and it was correct.
it's either B=6.25-1.25r or it's r=5-0.8b
