Length = x; width = y
2x+2y=88
x=2y+5
4y+10+2y=88
6y=78
y=13 feet
x=26+5
x=31 feet
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:
92
Step-by-step explanation:
w=7
x=4
y=8
z=1
8^2 + 2(4) + 3 (7) -1
64 + 2 * 4 + 3 * 7 -1
64 + 8 + 21 - 1
72 + 20
92
225. I think. However its not clear if total words typed are asked for Natasha or in General.
