Answer:
Step-by-step explanation:
Diameter=5 inches
Area= π
<u>r is the radius of coaster.</u>
<u>Radius=diameter/2</u>
Substitute the value of D:
r=5/2
Now
Area=π
Area=π()
Area=12.5π sq.inches
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
