She subtracted the coefficients instead of dividing them
Step-by-step explanation:
Answer:
- <u>Option A. about 100.5ft²</u>

Explanation:
Since the <em>bases</em> must not be painted, their areas are <em>not included</em> in the calculation.
The <em>surface</em> to paint, of each pillar, is equal to the lateral area of a<em> cylinder </em>with he dimensions given.
The formula for the laeral area of a cylinder is:
Substitute including the conversion factor to convert inches to feet:
To round up a number, you will add one value to the digit if the lower digit number is 5 or more. If the number is lower than 5, then you don't have to add one value.
In this case, you need to round up to hundred thousand. So, you need to look at the ten thousand digit which was 6. Since it was more than 5, you can add 1 value to the ten thousand digit. Then 362,584 will become 400,000
m<ABD = 52 Given
BC bisects <ABD Given
m<ABC = m<CBD Definition of angle bisector.
m<ABC +m<CBD = m<ABD Angle addition postulate.
m<ABC +m<CBD = 52 Substitution
m<ABC + m<ABC= 52 Substitution
2m<ABC = 52 Combining like angles
m<ABC = 26 Division property of equality.
0.37
0.194
0.6
0.473
0.29
the smallest digit at tenth place is 1 in 0.194, so 0.194 is the smallest here
