The right answer is Option D.
Step-by-step explanation:
Given,
Radius of basketball hoop = 9 inches
As the basketball hoop is in circular shape.
Circumference of basketball hoop = 2πr
We will put given radius = 9
Circumference of basketball hoop = 2*π*9
Circumference of basketball hoop = 2 . 9 . π
Therefore,
Circumference of basketball hoop is 2*9*π.
The right answer is Option D.

Answer:
Right triangle
Step-by-step explanation:
![{5}^{2} + {(5 \sqrt{3} )}^{2} = 25 + 75 = 100 \\ \\ {10}^{2} = 100 \\ \\ \implies \: {5}^{2} + {(5 \sqrt{3} )}^{2} = {10}^{2} \\](https://tex.z-dn.net/?f=%20%7B5%7D%5E%7B2%7D%20%20%2B%20%20%7B%285%20%5Csqrt%7B3%7D%20%29%7D%5E%7B2%7D%20%20%3D%2025%20%2B%2075%20%3D%20100%20%5C%5C%20%20%5C%5C%20%20%7B10%7D%5E%7B2%7D%20%20%3D%20100%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20%20%7B5%7D%5E%7B2%7D%20%20%2B%20%20%7B%285%20%5Csqrt%7B3%7D%20%29%7D%5E%7B2%7D%20%20%20%3D%20%20%7B10%7D%5E%7B2%7D%20%20%5C%5C%20%20)
So, by converse of Pythagoras theorem given side lengths form a right triangle
Answer:
A.
Step-by-step explanation:
Formula for the area of a circle is,
pi×radius squared
example,
radius of a circle is 2cm what's the area?use 3.14 as pi
2squared×pi
=2squared×3.14
=12.56cm squared..
hope this helps.....
