The distance from the outside edge of a circle to its centre is given by its radius. The circumference of a circle is given by 2πr, thus if we know that this is equal to 75 feet and using π = 3.14, we get:
75 = 2*3.14*r
r = 11.942
Thus r = 12 ft (to the nearest foot)
Answer:
I think the answer is b
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First, write 4 ½ in improper form. 2 × 4 + 1 = 9. So the fraction is 9/2.
Now divide:
9/2 ÷ 1/3
To divide by a fraction, multiply by the reciprocal:
9/2 × 3/1
27/2
13 1/2
Answer C.
Move all y terms to both sides
subtract both sides by 3xy
<span>y=3xy-1
y - 3xy = -1
factor out y from the left side: y(1 - 3x) = -1
divide both sides by (1-3x)
y = -1/(1-3x)
