Answer: 11
Step-by-step explanation:
Since the equation of circumference is 2(r)pi
if 22pi=2(r)pi
then 22=2r
22=2r
r=11

You can do it same way with B C and D
So assuming that the book is 100% the student has read 45% of the book so far in a time of 37 minutes so if you divide 45 by 37 you get 1 minute and 22 seconds per 1% of the assignment
If you multiply this by 100% you get 122 minutes for the total assignment
A circle and a triangle can intersect in a point.
<h3>What is intersection at a point?</h3>

Let the two numbers be x and y.
We have x+y=45
⇒ y= 45-x.
The two numbers multiply and get 121, so we have another equation:
x*y = 121 (1)
Plug y= 45-x in (1), we have:
x* (45-x)=121
⇒ 45x - x^2 = 121 (distributive property)
⇒ x^2 - 45x = -121 (multiply -1 on both sides)
⇒ x^2- 45x + 121= 0
⇒ x= 42.128 or x= 2.872
y= 45- 42.128= 2.872
or y= 45- 2.872= 42.128.
Because it does not matter what number, x or y, is larger, the two numbers are 2.872 and 42.128.
Hope this helps~
