circle A has a raduis that is twice the length og the raduis of circle B.
Which is an accurate statement about the relationship of these areas of circle A and B and y?
a.the area of circle A is 4 times the area of circle B
b. the area of circle A is twice the area of circle B.
c.the area of circle A is onehalf the area of circle B
d.the area of circle A is one forth the area of circle B
A = 3.14*r^2.
A = 3.14*(2r)^2 = 3.14*4r^2.
So the answer is a.
56
circle a=2x=28
circle b=x=14
you can make up your own lengths to make it easy
circle a=22/7x14x14=616
circle b=22/7x7x7=154
the area of circle b is bigger
that means circle a is four times the area of circle b
To find the relationship between the areas of circle A and circle B, we need to remember the formula for the area of a circle: A = πr^2, where A is the area and r is the radius.
Given that the radius of circle A is twice the length of the radius of circle B, we can denote the radius of circle B as 'r' and the radius of circle A as '2r'.
Now, let's calculate the areas of the two circles:
- Area of circle B = πr^2
- Area of circle A = π(2r)^2 = π(4r^2) = 4πr^2
Comparing the two areas, we can see that the area of circle A is 4 times the area of circle B.
Therefore, the correct option is a. The area of circle A is 4 times the area of circle B.
