Answer:
Step-by-step explanation:
Circumference of a circle = 2πr
where
r is the radius
To find the radius of the mat substitute the value of the circumference into the above formula and solve for the radius
Circumference = 200cm
200 = 2πr
Divide both sides by 2π
r = 31.83098
We have the final answer as
Hope this helps
let it be x then calculate
x+...+...= 360

n = 59
There's definitely a better way, i just did math randomly but here goes:
First i squared both sides. which gets you:
Cleaning this up gives you:
Now move everything to the other side so we can square this equation again
Divide both sides by -2
square again
subtract n^2 from both sides, add 6n, and add 50
Put this back into the equation and you get a correct answer!
sqrt(59 + 5) = sqrt(64) = 8
sqrt(59-10) = sqrt(49) = 7
8 - 7 = 1
