Be awesome! is a new cross fit gym in town. the gym is almost set to its grand opening. the contractors are doing flooring. gymnasium flooring cost $4.50 per square foot. the gym has 2 main rooms, one in a shape of a regular hexagon and the other in a shape of a regular nonagon. both rooms have side lengths of 50 feet. which of the following represents the closest estimate for the total of gymnasium flooring material? a: 29229 b: 4
c: 69545 d: 98774

D

Step-by-step explanation:

We need to find total area of the two rooms (hexagon and nonagon) and then multiply that by 4.5 to get total cost.

Area of Hexagon =

Where a is the side length (which is 50)

Hence,

Area of Hexagon =

Also, area of Nonagon is given by  

Where s is the length of the side

Hence,

Area of Nonagon =

Total floor area = 6495.2 + 15,454.5 = 21,949.7

Hence,

Total Cost = 21,949.7 * 4.5 = 98,773.65

THis is closest to the answer choice D.

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
