Answer: D) 226 m^2
Step-by-step explanation:
Equation: 2 x pi x r x h +2 x pi x r^2
2 x pi x 3 x 9 + 2 x pi x 3^2
<h3>
Answer: Choice B. p = 320(0.81)^t</h3>
Use the ^ symbol to indicate exponents. So for instance 4^2 = 4 squared.
A decrease of 19% means we have r = -0.19 and 1+r = 1+(-0.19) = 0.81 as the base of the exponent. A decrease of 19% means the population retains 81% each year.
4pi = w -6pi
Add the 6pi from both side
W=10pi
