A circular wading pool at a park has a radius of 21 feet. Find the circumference of the pool. Use 22/7 <span>for .
C=2πr=2·π·21
≈131.94689ft
</span>
131.95
76 cm,
(4•10=40)+((10-4)•6)= 76 units
I think the answer is A. 3.

C. no, to small a number
D. no, again, too big a number.
Have a nice day and hope this helps!
The circumference of the circle based on the equilateral triangle is 63mm.
<h3>How to calculate the circumference?</h3>
The side of the triangle is 20mm. The radius will be:
= 20/2 = 10
The circumference of the circle will be:
= 2πr
= 2 × 3.14 × 10
= 63
In conclusion, the circumference is 63mm.
