Answer:
1.16 is the answer
Step-by-step explanation:
For the answer to the question above,
A - C = ( -2, 9) - (- 2 -3)
<span>= ( 0, 12) </span>
<span>AC = 12 </span>
<span>B - C = (7 - 3) - ( - 2 -3) </span>
<span>= (9, 0) </span>
<span>BC = 9 </span>
<span>ABC is a right -angled triangle with AC as the hypotenuse </span>
<span>AC = sqrt( 9^2 + 12^2) </span>
<span>= sqrt(81 + 144) </span>
<span>= srqt(225) </span>
<span>= 15 </span>
<span>Perimeter = 12 + 9 + 15 </span>
<span>= 36 units </span>
<span> So the answer is 36 units
</span>I hope my answer helped you.
Answer:
48pi or ~150.8
Step-by-step explanation:
ok so area = pi * r^2
r = 8
8^2 = 64pi
so 64/4 = 16
16*3 quarters shaded = 48
48pi is the answer
48pi or ~150.8
I can’t see anything with the pictures
