Answer:
8
Step-by-step explanation:
Because 16 is the diameter and to find the radius you need to divide by 2
Split it into 7 triangles. Half-base of each is 2 so the distance of center to the midpoint of the base is (Pythagoras) square root of (4.62 - 22) = 4.162 triangle is this times 2, and with 7 triangles multiply also by 7 to get an approximate area of 58 sq in.
1280, -2560, 5120
Multiply the preceding term by -2 and
The rate of change is x2. So, since it's forty, it became 80 because 40x2=80!
Good luck for a good grade!
