(x-1)^2 is the factored version, so vertex is at 0, which is 1, so, A
Here is the required diagram .
Alternate angles are equal .
SA=4pir^2
d/2=r
d=7.4
7.4/2=3.7
SA=4pi3.7^2
SA=4pi13.69
SA=54.76pi
pi=3.14 for this question
SA=171.9464
closest one is B
172 cm^2
B IS ANSWER
Answer:
100 ft squared
Step-by-step explanation: you would usually round up to the nearest whole number with these and 9.7 would round to 10 and 10 times 10 would be 100
