A= 80
b= 100
c= 100
a is the same as the 80° already shown and to get b you have to subtract 80 from 180
Answer:
400
Step-by-step explanation:
first work out the radius of priya's circle with the equation a =



we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x
this means that if the diameter of dan's circle is 4 times bigger it must be
8x
to find the radius of dan's circle we divide the diameter by to 2 to give
4x 
then use the a=
equation again

which equals 400
hope that helped
Not clear.
Step-by-step explanation:
How much does the original mixture produce? is the original 1 quart? 1 gallon? 1 cup?
Divide both sides of the equation by the same term.
