Luis and his family flew 51487 miles last summer while on vacation rounded to the nearest thousand how many miles did they fly
ludmilkaskok [199]
In the given mathematical value of 51, 487 to round off this number to the nearest thousand, we can elaborate the number values using the expanded form to clearly see the order position: <span><span>1. </span><span> 50, 000 = ten thousands</span></span> <span><span>2. </span><span> 1, 000 = thousands</span></span> <span><span>3. </span><span> 400 = hundreds</span></span> <span><span>4. </span><span> 80 = tens</span></span> <span><span>5. </span><span> 7 = ones</span></span> Now we can observe the numerical value of 51, 487 than 1, 000 is the number in which belongs to the thousands’ position hence since the nearest number is 400 the value will be 51, 000.

Find the surface area of the composite solid. Round your answer to the nearest hundredth.
horrorfan [7]

Answer:

The answer is

A. 529.66 ft²

Step-by-step explanation:

The picture of the composite figure is not given,

But find attached the figure.

The composite consists of two solid shapes

1. Cylinder

2. Rectangular prism

To solve for the total surface area of the composite

Let us solve for the total surface area of the cylinder

Given radius r= 4ft

Height h=5ft

A= πr²+2πrh-πr²

N/B we subtracted the second circular surface since it is joined to the rectangular prism

A= 3.142*4²+2(3.142)*4*5-3.142*4²

A= 50.272+125.68-50.272

A=125.68ft²

We proceed to find the area of the rectangular prism

We know that the prism has 6 sides

Hence area

A= 2(11*6)+ 2(8*6)+2(11*8)

A= 132+96+176

A= 404ft²

Hence total surface area is

404+125.68= 529.68ft²
