Answer:
The approximate length of the radius, r is 12 inch.
Step-by-step explanation:
Given:
A circle P is given having circumference C,
C = 75 inch
pi = π = 3.14
radius = r
To Find:
radius = r = ?
Solution:
Circumference:
In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is the (linear) distance around it.
That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.
Formula is given as
Substituting the values we get
75 = 2 × 3.14 × r
∴
We approximate radius to
radius = 12 inich
Answer:
y = -11/6z - 6
Step-by-step explanation:
11z +6y = -36
-11z -11z
6y = -11z -36
----- ----- ----- divide by 6
6 6 6
y = - z -6
