Answer:
Step-by-step explanation:
Circumference is the perimeter of a circle. It can be found using the formula:
However, we are given the radius.
- The radius measures from the center to the edge of the circle.
- The diameter measures from edge to edge through the center.
- So, the diameter is twice the radius, or d=2r
The formula can be rewritten as:
We know the circumference is 25.12 inches.
Let's round pi to 3.14
We want to solve for the radius, so we must isolate it.
Divide both sides by 3.14 because the inverse of multiplication is division.
Divide both sides by 2.
The radius of the disc is <u>4 inches.</u>
Answer:
1/12 .......1/3 hour
we multiply by 12
12 *1/12.......12* 1/3 hours
fill completely in 12/3= 4 hours
Step-by-step explanation:
First u add ten to both sides to cancel out. Now you have 14=-7s. Since you are trying to do the opposite operation, you divide by -7 on each Sides. Now you have -2=s. Hope this helped
You can do 8*6 to find the area to be 48 ft. squared. So then we can do:
$1134/48 ft. to find the price per foot to be $23.63, or $24 rounded up
Hope this helps
Answer is C) 8/19
you do ((2*8)+3)/8
making it 19/8
and the reciprocal is the opposite of that answer, so 8/19
