It was 210 cm.
The function she used is h(t) = 210 + 33t. This is a linear function, since it is of the form f(x) = mx+b. In a linear function, we have the slope, m, which tells us how much the height increases per year, and the y-intercept, b, which tells us how tall it was when we began measuring. Our m value would be 33 and our b would be 210, so the original height was 210.
the answer to this question is C
Your question: Find 40% of 200
======================================================================
SOLVING...
Multiply 40% (or 0.40) by 200 to find your answer
40% x 200 = 80
0.40 x 200 = 80
80 is your answer
The answer is 162 81pi/2
Hope this helps!
the area is (1/2) x pix 9^2 = 81pi over 218.9=162162-81pi over 2
