A concrete molding to support a highway bridge is formed by six cylinders 2.1 m in diameter and 10.5 m high surmounted by a prismatic crosspiece whose dimensions are 31.5 m in length by 3.15 m in width and 2.1 m in height.

To paint this structure in white, how many square meters will we have to paint?

Use the approximation π ≈ 3.1416 or the value of the calculator and round your answer to the nearest tenth.

it would be 6xy and -16xy.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
