Answer:
B. 26.99 ft.
Step-by-step explanation:
The formulas for circumference (C) and area (A) are ...
A = πr²
C = 2πr
Solving the area formula for r, we get ...
r = √(A/π)
Substituting this into the circumference formula gives ...
C = 2π√(A/π) = 2√(πA)
For the given circle, the numbers are ...
C = 2√(3.14×58 ft²) ≈ 26.99 ft
If he has read 56 pages and there are a total of 490, then how many are left? That's 490 - 56 = 434.
To read 434 pages in 6 weeks, he should read 434 / 6 pages each week. That's 72 1/3 pages per week.
See the graph lines.. notice since it’s < you need to use a dash line.
Answer: D. Square
The cross section is shown as the shaded region. There are four sides to the shaded figure, so the cross section is a quadrilateral. This rules out choice C. We can also cross choice B off the list because cross sections of 3D figures are 2 dimensional.
Choice A is ruled out as well because we have both pairs of opposite sides that are parallel. The only thing left is choice D. This is true assuming we have a square prism. Any cube is a square prism that has its height equal to the width and length.
Multiply and combine similar variables, using the rules of exponents. So your answer is A to the power of 9.
