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
