Answer:
363
Step-by-step explanation:
Formula for area of a circle
A = πr^2
Where r = radius
The circle has a given radius of 11
To find the area of the circle we simply substitute r in the formula with the value of the radius (11)
( Also note that the question says to use 3 for π )
A = πr^2
π = 3
r = 11
Substitute values in formula
A = (3)(11)^2
11^2 = 121
A = 121(3)
121(3) = 363
A = 363

Fitness levels can be measured by simple tests, such as counting the number of crunches you can do in two minutes.
First subtract the two numbers:
8 - 5 = 3
Now divide this to the original:
3 / 5 = 0.6
Multiply by 100:
0.6 * 100 = 60%
2x+6 = 20
take 6 from both sides
2x = 14
divide by 2 on both sides
x = 7
