Answer:

Step-by-step explanation:
3a²*2a³ = (2*3)(a² *a³)= 
The correct answer is the third choice, Quadrilateral.
Answer:
Diameter 16, radius 7, circumference 37.68, diameter 8
Step-by-step explanation:
Largest area will be in a circle with the largest radius. So let's find all radii.
d = 8, so r = 4;
r = 7;
circumference = 2pi*r = 37. 68, so r = 6
diameter 18, so r = 8
5. The answer is D

because it says no more than 160 so it's possible to be equal to 160.
6.

So the answer is A
