Answer:
a. the diameter is <u><em>127.324 yards</em></u>
b. The area is <u><em>12732.385</em></u> yards^2
Step-by-step explanation:
The circumference of the circle is 400, and to get circumference from diameter, multiply it by π, so we divide by pi to get the diameter. 400/π = 127.324
The area of a circle is πr^2. To find r, or radius, divide the diameter by 2 to get 63.662. So it is 63.662^2π. 63.662^2 = 4052.844, so 4052.844π, and now we get 12732.385
Answer:
I think its B its the only one that makes sense to me
Step-by-step explanation:
Answer:
last option at the bottom.
Step-by-step explanation:
we are told that the the equation
y = 0.73x + 1 represents the Length of the spring when a stretch force is applied,
basically y = length of spring and x = force applied.
from the graph, we can see that when stretch force = 0 (i.e x = 0)
the equation becomes y = 1.
That is to say that the spring has a length of 1 inch when stretch force is zero
(which basically is the same as the last option)
Answer:
Step-by-step explanation:
2x + 3 = 1
Collecting like terms
2x = 1 - 3
2x = -2
x = -2/2
x = -1
