Just did the test on edgenuity
Answer: CSA = 22.9m^2
Step-by-step explanation:
The cross sectional area of the cylinder perpendicular to the length, is the area of the circular base or top of the cylinder. It can be derived mathematically using the area of a circle.
Cross sectional area = πr^2
Where r is the radius of the cylinder
r = 2.70m
CSA = π×2.70^2
CSA = 22.9m^2
Since the 9 is greater than or equal to 5, we'll round our number up by adding 1 to the 3 in the hundreds place, making it a 4. And also by changing all digits to the right of this new 4 into zeros.
And our rounded number would be 400
The correct answer would be B. Because if you multiply -25 * -25 (because the x has 2 to the second power) the answer would be 625 :)
Hope I helped.
