Answer:
Step-by-step explanation:
The formula for volume of a cylinder is..
V = πr²h where r is the radius and h is the height. We are given V = 452 and h = 9, plug those values in and solve for r
452 = πr²(9)
452/(9π) = r² (divide both sides by 9π)
√[452/(9π)] = r (take the square root of both sides)
(√452)/(√9π) = r (the next steps simplify the equation)
(2√113)/(3√π) = r
[(2√113)√π)]/[3(√π)(√π)] = r
[2√(113π)]/(3π) = r
I believe the correct answer is A. 0.87
On any given day, the probability that a person chosen at random will visit either Willow Creek or Two Harbors is <span>0.87
How did I get this?
62% = 0.62 73% = 0.73 48% = 0.48
( 0.62 + 0.73 ) - 0.48
*Sorry had to correct it I did the math again and got 0.87*</span>
Its greater by a factor of 2^2 ( = 4)
Its 4 times the area of the original square.
