<span>Surface area</span> = 2πr(h+r) = 2 * 3.14 * 3(8+3) = 207.24 yd²
Answer:
216
Step-by-step explanation:
♥ Lets solve this:
(7*10^5)^2(7*10^5)^2
Starting with 10^5
10*10*10*10*10
We get <span>100000
<span>Now we have 7*100000
Solve for that:
We get </span></span><span>700000
Now we have </span><span>700000^2
Solve for that
We get </span><span>490000000000
and in Scientific notation that is
4.9*10^11</span>
Choice A is the correct answer
He divided the wrong way. 7/33 = .2121.....and 2/11 = .1818...., so actually 2/11 < 7/33
