So 9.42 is the circumference 9.42/3.14 is 3 and 3 is your diameter 1.5 is your radius and area is radius times radius then times pi so 1.5 x 1.5 = 2.25
2.25 x 3.14= 7.06500 so I believe your answer is about 7 units
the second 3 (from the left) is in the hundreds place so we look at the 1st 7 (from the left) to determine how to round
since 7 is 5 or greater, we round the 3 to a 4
3400
Choice D
The answer is true as the y value of y=sin
I believe you set them equal to each other.
2x+4=5x-9
x=4.3
2(4.3)+4=12.6
I think the answer is 12.6
