Diameter = radius x 2
So, the radius is half of the denominator.
10 / 2 = 5
A = pi x r^2
A = pi x 5^2
A = 3 x 25
A = 75 ft^2
Hope this helps!
In order to know that, you need to divide it from other, if it would be perfect number then your answer will be "YES" & if they not then it will be "NO"
35/100 / 5/100
You can re-write it as:
35/100 * 100/5 = 35/5 = 7
So, they are proportional to each other,.
Hope this helps!
Lol I'm glad to answer your questions :D
So in the last question, it uses the word "per" which basically means you would have to multiply the number of pounds times 1.69
So it would be $1.69a
There are 20 cups and each one holds 10 fluid ounces. Assuming that she wants to fill them all up to the brim and use the complete 10 fluid ounces for each cup this means she would have a total of 200 fluid ounces: 20 * 10 = 200
1 gallon = 4 quarts
1 quart = 32 fluid ounces
This means that for every gallon she has 128 fluid ounces: 1 gallon (4 quarts/1gallon)(32 fluid ounces/1 quart) = 128
This means she needs at least 200 fluid ounces and she must buy another gallon to satisfy this; 128 * 2 = 256 fluid ounces.
She needs to buy 2 gallons but will have an extra 56 fluid ounces
