Surface area = 4* pi * radius squared
radius is half the diameter
4 *3.14 * 2^2 = 50.27
With percentage in the question, you divide the miles they drove by the total miles in the trip (and of course multiply it by 100).
Joe:
.3077 times 100= 31% (just rounded the percentage to the nearest whole number).
Adam:
.5385 times 100= 54%
Laura:
.1538 times 100= 15%
Tell me if this helps!!
Its PQN≈STR because clearly the rest aren’t right and plus p goes with s q pairs with t and n pairs with r
Slope intercept form is y=mx+b, therefore your answer is D.
Hope this helped :)
