Vaughn paints his porch floor and also the porch floors of 9 neighbors. Each floor is a rectangle that is 8.2 feet long and 6.7 feet wide. Part A Which equations represent the best estimate of the total area of all the porch floors that Vaughn paints? A. 8 × 6 = 48; 48 × 9 = 432 square feet B. 8 × 7 = 56; 56 × 10 = 560 square feet C. 10 × 7 = 70; 70 × 10 = 700 square feet D. 10 × 10 = 100; 100 × 9 = 900 square feet 00:00 Part B What is the exact total area of all the porch floors that Vaughn paints? Enter your answer in the box. square feet 00:00 Part C Compare the estimate to the exact answer. Use the drop-down boxes to explain whether your answer is reasonable. The estimate is square feet from the actual answer. So, the answer reasonable.

Cone w has a radius of 8 cm and a height of 5 cm. square pyramid x has the same base area and height as cone w. paul and manuel disagree on how the volumes of cone w and square pyramid x are related. examine their arguments. which statement explains whose argument is correct and why? paul manuel the volume of square pyramid x is equal to the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is three times the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is (area of base)(h) = (200.96)(5) = 1,004.8 cm3. paul's argument is correct; manuel used the incorrect formula to find the volume of square pyramid x. paul's argument is correct; manuel used the incorrect base area to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect formula to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect base area to find the volume of square pyramid x.
