Answer:
25.12
Step-by-step explanation:
C = 2pir
2 * pi = 6.28, 6.28 * 4 = 25.12
To find<span> the perimeter of the </span>quarter circle<span>, </span>find<span> the circumference of the whole </span>circle<span>, divide by 4, and then add the radius twice. To </span>find<span> the radius when you are given the </span>area<span> of the </span>quarter circle<span>, multiply the given </span>area<span> by 4, then plug this number in for A into the formula A = pi * r^2 and then solve for r.</span>
Step-by-step explanation:
A cyclic quadrilateral is a quadrilateral whose vertices all lie on a single circle. A convex quadrilateral ABCD is cyclic if and only if its opposite angles are supplementary, means
∠q + 58 =180
∠q = 180 -58
∠q = 122 degree
∠p + 90 = 180
∠p = 180 -90
∠p = 90 degree
Answer:
68.269%
Step-by-step explanation:
We start by calculating the z-scores of both numbers
Mathematically;
z-score = (x-mean)/SD
where x represents the raw score
For 82;
z-score = (82-87)/5 = -5/5 = -1
For 92;
z-score = (92-87)/5 = 5/5 = 1
So the probability we want to calculate would be;
P(-1 < x< 1)
We can use the standard normal distribution table to get this.
By using the distribution, P(-1<x<1) = 0.68269
By converting this to percentage, we have 68.269%
Answer:
