Results: From a purely mathematical point of view, the special with two large pizzas is a slightly better deal, pricing the pizza at 4.97 cents per square inch.Īdditional Details: My eight-grade math teacher, Mr. In column H, calculate the dollars per square inch of pizza, using =G2/F2. Enter the cost for the special in column G.

Calculate the total square inches in column F by using =E2*D2.In column E, enter the quantity of pizzas.What is the area of his hole Area of the hole is 113.1 square feet. The area of a circle(A) when the radius r is given is r2. Area r2 x 22 x 4 12.6 square yards 2) Captain digs a 12-foot wide circular hole in his garden. The area of a circle is multiplied by the square of the radius. In cell D2, calculate the area of the pizza in square inches, using =PI()*C2^2. AREA OF A CIRCLE WORD PROBLEMS 1A ANSWERS Working out 1) A circular pond has a radius of 2 yards.In cell C2, calculate the radius as =B2/2.In cell B2, enter the diameter of the pizza. Here's how you determine which is the better pizza deal: =PI() returns the value of pi to 15-digit precision.It is a lot easier to remember =PI() than the many digits in 3.141592654. Excel offers the PI function to return this number. Pi is a Greek letter that represents 3.141592654. If you enter the diameter of the pizza in B2, the radius is =B2/2. The radius of a pizza is one-half the diameter. The formula for the area of a circle is pi * r 2 (where r is the radius). So the final answer is 49 m2 (put the number before pi and put your answer in terms of the relevant units squared). Just enter the value of the radius and hit. All you need to do is substitute 7 for r in A r². The following area of a circle calculator will help you find the area of any circle when the radius is given. Calculate the Diameter of a Circle, from Its Area (or Vice Versa) Divide the area (in square units) by Pi (approximately 3.14159). Strategy: You will have to figure out the area of a 12" pizza vs. Work out the area of a circle that has a radius of 7 m. I can buy three medium (12") pizzas for $18 or two large (16") pizzas for $20. Problem: I need to order pizza for my department's staff meeting.
