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:
Dependent
Step-by-step explanation:
Because there is only one function to the equation.
Let us assume the width of the rectangle = x meters
Then
Length of the rectangle = 2x + 2
Perimeter of the rectangle = 16 meters
Then
Perimeter = 2 (Length + width)
16 = 2(2x + 2 + x)
16 = 2(3x + 2)
16 = 6x + 4
6x = 16 - 4
6x = 12
x = 2
Then
Length of the side of the rectangle = 2x + 2
= (2 * 2) + 2
= 6
I hope that the procedure is clear enough for you to understand and this is the answer that you were looking for.
