GIVEN:
The price of pizza is proportional to the square of radius of pizza and 3 pizzas of radius 6 cm each costs Rs.486.
CONCEPT:
Basic ratio concept.
CALCULATION:
Price of pizza is proportional to the square of radius of pizza.
Price of one pizza of radius 6 cm = 486/3 = Rs.162
Price of one pizza of radius 8 cm = 162 × (82/62) = Rs.288
So,
Price of two pizzas of radius 8 cm each = 288 × 2 = Rs.576
