Use the pythagorean theorem
input your values
solve
then square root 'c'
these options are for if your teacher wants it in radical form as mine had
Check the picture below.
let's notice those two corresponding angles of 90° - 2x, and also recall that the sum of all interior angles in a triangle is 180°.
Total number of beads = 3 + 8 + 7 = 18. P(red) = total number of red/total number of beads = 3/18 = 1/6. P(blue) = total number of blue beads/total number of beads left after replacement = 8/17. P(black) = total number of black beads/total number of beads left after replacement = 7/16. Therefore P(red) = 1/6. P(blue) = 8/17. P(black) = 7/16.
Since the circle is inside the square, the diameter of the circle is the same length as a side of the square.
The length of the side of the square is found by taking the square root of the area:
Side length = SQRT(144) = 12 m
The circumference of a circle is found by multiplying the diameter by PI:
12 x 3.14 = 37.68 = 37.7 m
