Answer: The radius of the circular rug is 6 meters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
<em>Area of a circle (A) = pi r²
</em>
Where r is the radius:
Replacing with the values given:
36 pi=pi r²
Dividing both sides by pi:
36 = r²
√36= r
r = 6 meters
So, the radius of the circular rug is 6 meters.

Answer
Step-by-step explanation:
A=2πrh+2πr2=2·π·3·6+2·π·32≈169.646
Step-by-step explanation:
You can set up a proportion.
Let x be the number of pencils needed.
Solve for x.
x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)
S = 32 and t = 45
You replace the letters into numbers...
Since (st) is the same thing as (s × t), it would be 32 × 45, which equals to 1,440.
Then replace the r with 5, so now it's (6 × 5), instead of (6r).
st ÷ (6r) → 1,440 ÷ 30 = 48
Value of st ÷ (6r) = 48
