Two circular pizzas have radii in the ratio 2:3. If the smaller pizza has an area of 100π cm2, what is the area of the larger pizza?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 225π cm2.
Radii ratio = 2 : 3
Area ∝ (radius)2
Area ratio = 22 : 32 = 4 : 9
Smaller pizza area = 100π
Larger area = = 225π cm2
