Answer:
Step-by-step explanation:
error in measurement = 480 - 469 = 11 inches
Percent error = error *100/actual length
= 11 * 100 /480 = 2.9%
The area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
<h3>What is the area of the circle?</h3>
The area of the circle is the space occupied by it. It is the product of pi and square of its diameter divided by 4. The area of the circle can be given as,
![A=\pi\dfrac{d^2}{4}](https://tex.z-dn.net/?f=A%3D%5Cpi%5Cdfrac%7Bd%5E2%7D%7B4%7D)
Here (d) is the diameter of the circle. The diameter of the circle is 6 cm.
![d=6](https://tex.z-dn.net/?f=d%3D6)
Put this value in the above formula to find the area of the circle as,
![A=\pi\dfrac{6^2}{4}\\A=\pi\dfrac{36}{4}\\A=\pi\times9\\A=9\pi\rm\; cm](https://tex.z-dn.net/?f=A%3D%5Cpi%5Cdfrac%7B6%5E2%7D%7B4%7D%5C%5CA%3D%5Cpi%5Cdfrac%7B36%7D%7B4%7D%5C%5CA%3D%5Cpi%5Ctimes9%5C%5CA%3D9%5Cpi%5Crm%5C%3B%20cm)
Thus, the area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.

Answer:
5 friends
Step-by-step explanation:
Candy pieces = 60
Chocolate = 45
What should be the smallest number of her sister's friends for the distribution of candy and chocolate so each friend gets an equal number of candy pieces and chocolates in a way that there should not be left any chocolate or candy pieces left over?
To calculate this, find the lowest factor of 60 and 45
60:
Factors = 2, 4, 5, 6,
45:
Factors= 3, 5, 9
The lowest common factor of 60 and 45 is 5
The smallest number of her sister's friend so each person get an equal number of candy pieces and chocolate so there won't be any leftover is 5
That is
If there are 5 friends at the birthday party
60 candy pieces among 5 friends
= 60/5
= 12 pieces each
45 chocolate among 5 friends
= 45/5
= 9 each
