So, imagine the trainer is in the very middle of the circle and he is holding out a rope that's attached to the horse. The rope here from the trainer to the horse represents the radius of the circle. The horse trots around the trainer (middle point) in a circle.
The formula to find area of a circle is A = pi*r^2 (pi times r squared where r is radius)
We know that the radius of the "circle" here formed as the horse trots around the trainer is 31 (the 31 foot long rope).
So let r = 31 & plug the value into the formula to find circle area.
A = pi*31^2 = 3019.07054
The area is therefore 3019.07 square feet. (rounded)
Answer:
15/4
Step-by-step explanation:
Fractions are basically division problems you divide the nominator by the denominator
Answer:
C
HOWEVER: "Less Than" is usually depicted as a dashed line at the border. and there MUST be an OR between these two equations to include all of the blue area. An "and" there would exclude the area between the edge lines.
Step-by-step explanation:
2x + y < 10
y < -2x + 10
3x + 2y < 12
2y < -3x + 12
y < -1.5x + 6
In the figure we have the graphic of this equation. So, the vertex is the maximum of this function. This point means that the maximum <span>daily profit from soccer balls is:
</span>
<span>
And this happens when the </span><span>selling price of each soccer ball is:
</span>
<span>
So if you want to get the best daily profit, this is the price you must sell each soccer ball.</span>
Answer: 7/12
Step-by-step explanation:
From numbers 1 - 12, there are seven numbers greater than 5 so they probability of rolling a number greater than 5 is 7/ 12
