Answer:
<u>A</u>
Step-by-step explanation:
<u>Given equation</u> :
<u>Evaluating the options</u>
<u>A (-2, 5)</u>
R = 6.5cm and r = 2.3 cm
area of the shaded region = area of the outer circle - area of the inner circle
= πR²-πr²
=π(R²-r²)
=π{(6.5)²-(2.3)²}
=π (42.25-5.29)
= 3.14× 36.96
= 115.866
= 116 cm²
-1, -24
-9-(-8)
double negative = positive
-9+8=-1
21-45=-24
