Answer:
21.98 yards
Step-by-step explanation:
In this question, we are asked to get the distance from a flag placed at the center of a garden to the edge of that garden.
From the definition of circle terms, the radius of a circle is simply the distance from the center of the circle to any part of the circumference(in this case, edge of the circle)
Since we are given the circumference of the circle, all we need to do to know the distance is to look for the value of the radius. Hence, we use the formula that links the circumference of a circle and the radius of the circle.
Mathematically, the circumference of a circle C=2πr
The value π is 22/7
138.16 = 2 * 22/7 * r
44r = 7 * 138.16
r = (7 * 138.16)/44
r = 21.98 yards
Hence the distance from the center of the circular garden to its edge is 21.98 yards
It depends on what you draw. So I'd like to say C, because you could pull up all the white marbles the first few draws, or none the first few and every other marble. It really depends.
Answer:
10 inches
Step-by-step explanation:
The formula for the triangle area is the following:
A = b * h / 2
Where b is the length of the base side and h is the height.
So, as the height is 4 less than the base, we have that:
h = b - 4
Using this value in the area equation, we have that:
A = b * (b - 4) / 2
30 = (b^2 - 4b) / 2
b^2 - 4b = 60
b^2 - 4b - 60 = 0
Using Bhaskara's formula to solve the quadratic equation, we have:
Delta = 4^2 + 4*60 = 256
sqrt(Delta) = 16
b1 = (4 + 16)/2 = 10
b2 = (4 - 16)/2 = -6 (negative value does not fit for this problem)
So the length of the base is 10 inches.
The results will always equal a positive
