Is the question complete or is that 0.25?
Use distrubutive property <em>a(b + c) = ab + ac</em>
6(5r - 4) - 2(r - 7s - 3)
= (6)(5r) + (6)(-4) + (-2)(r) + (-2)(-7s) + (-2)(-3)
= 30r - 24 - 2r + 14s + 6
= (30r - 2r) + 14s + (-24 + 6)
<h3>= 28r + 14s - 18</h3>
Answer:
6.25pi
Step-by-step explanation:
If the circumference is 5pi, then the radius has to be 2.5
Plug that into the area of a circle formula, (pi)(r^2) so your answer is 6.25pi.
