Oh, dude, you're hitting me with some math at this hour? Alright, so the area of a circle is πr^2, which means you just gotta plug in the radius of 9 inches and do some quick calculations. So, the area of that Pizza would be around 254.47 square inches. But hey, who's really counting when you're about to chow down on some delicious pizza, am I right?
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
7.952 square inches
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.
A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.
A circle with a radius of 9 feet has an area of 254.47 square feet.
9 inches is your radius. Use that to calculate the area of the whole pizza and then divide by 8. (You do not need any sections or angles).
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches
254.47 square inches.
2 inch radius = 12 9/16" circumference & an area of 12.56637 sq. inches.
That depends on the radius of each pizza (and how close to the edge the toppings go.) Let's call the small pizza a 6 inch pizza - that's a radius of 3 inches and a total area of 9(pi) square inches or 28.2744 square inches. At 5.95 that's 4.752 square inches per dollar. For a pizza costing 9.95 to be better value the square area would need to be 47.2824, which when divided by pi gives a radius of 3.879 inches - and a diameter of 7.758. So, if the large pizza is over an inch and a quarter wider, and if the toppings are proportionately distributed, then the large pizza is better value...... but only if you're going to eat it all. If you don't eat it all then you'll have paid more and eaten the same amount..
The circle's radius is 1.5/2 = 0.75 ft = 9 inches The area of the circle is (pi) times (radius)2 = (pi) x (9)2 = 254.469 square inches (rounded)
9 inches.
