Answer:
A. x^2 + y^2 = 36
Step-by-step explanation:
The equation of a circle is usually written in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
The center is at the origin so (h,k) = (0,0) and the radius is 6 so r=6
x^2 + y^2 = 6^2
or x^2 +y^2 = 36
Answer:
.375
Step-by-step explanation:
divide 3 by 8
Answer:
About 43.96, 153.86
Step-by-step explanation:
1. Finding the Circumference:
The formula for the circumference is 2 * pi * r. The formula for radius is diameter/2 , which is 14/2 = 7.
Now if we round pi to 3.14 , this is 2 * 3.14 * 7 = 43.96
2. Finding the area
The area for a circle is equal to πr^2. And if we know the radius is 7, if we round pi to 3.14, we get 153.86 inches
Hope you at least get the jist of it!!
