C because the formula to find the are of a circle is A=(pi) * radius^2. To find the radius from diameter, just divide by two. So 60/2= 30 so now you can just plug in and 30 * 30 is 900 and 900 * pi, or 3.1415926535, is about 2827
B and C are equivalent while A and D are not

We need to find if the expression 23.6/4.02 is equivalent to any of the below.
23.6/4.02 = 5.8706
A) 2.36/40.2 = is not equivalent to above expression as the numerator and denominator both are not multiplied with the same number.
B) 2360/402 = 23.6/4.02 , both numerator and denominator are multiplied with 100 so it is equivalent to the above expression
C) 2.36/0.402 = 23.6/4.02 as both numerator and denominator are multiplied by 0.1 so it is equivalent to the above expression
D) 236/4020 = is not equivalent as the numerator and denominator are not multiplied with the same numbers
Answer:

Answer:
11 and 12
Step-by-step explanation:
√123 ≈ 11.0905 lies between 11 and 12.
__
Since you're familiar with your squares, you know ...
11^2 = 121
12^2 = 144
123 lies between 121 and 144, so √123 lies between 11 and 12.
To start, find the area of the triangles. The formula for the area is B times H divided by 2. To find the base, add 1.5 plus 1.5. The answer to that is 3, so the base is 3. The height is 2.6, so now you need to multiply 3 by 2.6. The answer to that is 7.8, so the last step to find the area is 7.8 divided by two. The answer to that is 3.9, but there is also another triangle on the back of the triangular prism, so 3.9 times 2 is 7.8. Yes, I know you could just easily just do 7.8 as the answer to both areas, but whatever, we already did that. The second to last step of finding the surface area is finding the area of the rectangle faces. The formula for that is L times W, so the length is 5 and the width is 3. Multiplying those together gives us the answer of 15, and since there are two rectangles, the final area of both rectangles is 30. The last step is to add 7.8 to 30, giving us the final surface area of 37.8!
