$57.75 because 14 divided by .25 is 56 and then plus the first mile is 57.75
Answer:
The answer is
<h2>660.5 square feet</h2>
Step-by-step explanation:
Area of a circle = πr²
where r is the radius
From the question
diameter = 29 feet
To find the radius given the diameter we use the formula
So the area of the circle is
We have the final answer as
<h3>660.5 square feet</h3>
Hope this helps you
Volume of the box= <span>56 cubic inches
let x is the length, then
width =</span><span>2 inches shorter than its length = x - 2
</span>height = <span>3 inches taller than its length = x+3
Volume = length x width x height
56 = x x (x-2) x (x+3)
56 = (x</span>² -2x)(x+3)
56 = x³ +3x² -2x² - 6x
56 = x³ + x² -6x
x³+x²-6x-56 = 0
using the rational root theorem and factoring the polynomial;
(x-4)(x² +5x +14) = 0
from here;
x-4 = 0
x = 4
So, length = 4 inches
width = x - 2 = 4 -2 = 2 inches
length = x + 3 = 4 + 3 = 7 inches
volume = l x w x h = 4 x 2 x 7 = 56
