Trina uses 1/2cup of sugar and 3/4 cup of flour in a recipe. how many cups of sugar would she need if she uses 3 cups of flour?

2 cups of sugar

Step-by-step explanation:

Trina uses the number of cups of sugar in a recipe =  

                                                                                     = 0.5 cups

she uses the number of cups of flour in a recipe =  

                                                                                = 0.75 cups

The proportion of sugar and flour she uses =  

Let the sugar would be needed for 3 cups of flour = x

Therefore,   ×  

x = 2

She would be needed 2 cups of sugar.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
