Mr.Ferris discovered in his 2013 copy of the world records book that the worlds largest pizza measured 5.83 feet in diameter. A regular pizza measures 0.6 feet in diameter. How much greater is the area of the larger rice cake?
No idea about rice cakes, but if we're talking about pizzas,
greater by a factor of (5.83/0.6)^2
The area is greater by (5.83^2 - 0.6^2)π
rice cake?????
To calculate the area of a circle, we use the formula:
A = π * r^2
Where A represents the area and r represents the radius of the circle.
First, let's calculate the area of the regular pizza:
Given that the diameter of the regular pizza is 0.6 feet, we can find the radius by dividing the diameter by 2:
Radius of regular pizza = 0.6 / 2 = 0.3 feet
Substituting the radius (0.3 feet) into the formula:
Area of regular pizza = π * (0.3)^2 = π * 0.09 ≈ 0.283 square feet
Now, let's calculate the area of the largest pizza:
Given that the diameter of the largest pizza is 5.83 feet, we can find the radius by dividing the diameter by 2:
Radius of largest pizza = 5.83 / 2 = 2.915 feet
Substituting the radius (2.915 feet) into the formula:
Area of largest pizza = π * (2.915)^2 ≈ π * 8.4989 ≈ 26.724 square feet
To find the difference in area between the largest and regular pizza, we subtract the area of the regular pizza from the area of the largest pizza:
Difference = Area of largest pizza - Area of regular pizza
= 26.724 - 0.283
≈ 26.441 square feet
Therefore, the area of the larger pizza is approximately 26.441 square feet greater than the regular pizza.
