21 is to 75 as 7 is to 25 . We can now change 25 to 100 by multiplying by 4 . Therefore , on also multiplying 7 by 4: 21 is 28% of 75
The perimeter is 320. Just multiply 80 times 4
I'm not in High School (Me is in Middle School) so... But, I got B.
Use the Circumference Formula of a Circle: C=2(pi)(r). The radius is the length from the center to a point on the circle. The circumference is essentially the perimeter of the circle, so the “edge” around the circle is the circumference.
Hi!
We are given the information found in the picture below.
Note: The directions aren't correct, but the triangle works for this problem.
The "direct path" is the hypotenuse of this triangle.
To find this, we use the Pythagorean Theorem, where and are 2 legs of the triangle, and is the hypotenuse, aka the longest side of any triangle:
We know and and want
Therefore, is approximately
