Apply the law of multiple proportions to the two compounds. For each compound, find the grams of copper that combine with 1.00 g of chlorine by dividing the mass of copper by the mass of chlorine. Then find the ratio of the masses of copper in the two compounds by dividing the larger value by the smaller value.

Okey so the area of a circle is taken from the equation πr²
now in the sum they have given information as: area of one small circle is 9π
that means :
area of small circle = πr²
= π3²
= π9
so in the sum they have given us the radius of one circle as 3
from this information we understand that the diameter of one small circle should be = 3 ×2
= 6 (as diameter is twice the radius)
we are given 3 of these circles. that means there are 3 times the diameter measured.
so the diameter of the large circle is = 6×3 = 18
as we calculated, since 18 is the diameter of the large circle, it should be taken ½ for radius.
radius of large circle = 18÷2
= 9
now we know the radius of large circle.
taking the equation 'πr²' to find the area:
area of large circle = πr²
= π9²
= π81
your answer is 81π

Hey! The correct answer is 55.
Answer:
Mean. It includes all data points.
Step-by-step explanation:
-We first need to calculate the mean, median and mode then compare our values:
#Mean:
#The median is the middlemost data point in a lsit data:
778,783,784,786,790,804,807,810,819,823
-Since our data points is an even number, the median number is calculated as:
#Mode is the data point with the highest frequency:
-Since there's no number appearing more than once, our set has no mode.
#Since our data set has no outliers and is not a skewed distribution, the mean will be the best measure as it includes all data points
