2.26 x 10 to the 12 power or 2,260,000,000,000
V= π r^2 h/3
V= π 4^2 9/3
V= π 16 3
V= 150.72
V=151
Explanation
Formula is the first line. R is the radius with us 4 and h is the height which is 9. Substituting these values into the formula will get you pi times 4 squared times 9 divided by 3. When simplified this gets pi times 16 times 3. Using the approximate value of pi which is 3.14, multiple it with 16 and 3 will get you 150.72, round this to 150.8, which rounds to 151.
Hope this helps
You are correct, it’s a(x). Because the y-intercept of b(x) is 2 and the y-intercept of a(x) is 3 … which just so happens to be more than 2
