The formula to find the circumference of a circle is 2 x pi (π) x radius. The radius is half of the diameter. Therefore, since the diameter is 20, the radius is 10. Pi is equal to approximately 3.14.
3.14 x 10 x 2 is 62.8.
The circumference of the circle is 62.8 m.
Answer:
x^5/6 + 2x^7/3.
Step-by-step explanation:
x^1/3 ( x^1/2 + 2x^2 )
= x^(1/3 + 1/2) + 2x^(1/3 + 2)
= x^5/6 + 2x^7/3
