Answer: B. Cone

Step-by-step explanation:

In geometry, a solid cone is a three-dimensional shape that has a flat circular base, and a point called the apex or vertex such that it tapers from a circular base to a apex.

Therefore by the definition of cone , according to the given information if a image contains a circle and above a cone with 5 cm.

Then the figure created can be a cone.

A rectangular box has a length of 8 feet and a width of 2 feet. The length of the three-dimensional diagonal is 10 feet. What is

harkovskaia [24]

Answer: $h=5.66ft$

Step-by-step explanation:

Observe the picture attached.

Find the value of "x" and "y" using the Pythagoren Theorem:

$a^2=b^2+c^2$

If you solve for "a":

$a= \sqrt{b^2+c^2}$

Where "a" is the hypotenuse and "b" and "c" are the legs.

In this case, for "x" you know that:

$a=x\\b=8ft\\c=2ft$

Then, the value of "x" is:

$x=\sqrt{(8ft)^2+(2ft)^2}\\\\x=8.24ft$

For "y" you can see that:

$a=10ft\\b=8.24ft\\c=h$

Subsituting values and solving for h, you get:

$(10ft)^2=(8.24ft)^2+h^2\\\\h=\sqrt{(10ft)^2-(8.24ft)^2} \\\\h=5.66ft$

Find the surface area of the composite solid. Round your answer to the nearest hundredth.

iogann1982 [59]

The surface area of the composite solid is 579.84 square feet

<h3>How to determine the surface area of the solid?</h3>

The composite solid that completes the question is added as an attachment

From the attached figure, we have the following figures:

Rectangular prism
Cylinder

The surface area of a rectangular prism is

A = 2(lw + lh + wh)

Using the dimensions of the prism, we have:

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

This gives

A = 404

The surface area of a cylinder is

A = 2πr^2 + 2πrh

Using the dimensions of the cylinder, we have:

A = 2 * 3.14 * 4^2 + 2 * 3.14 * 4 * 5

Evaluate

A = 226.08

The area of the circle between both shapes is

A = πr^2

This gives

A = 3.14 * 4^2

A = 50.24

The surface area of the composite solid is then calculated as:

Surface area = Area of rectangular prism + Area of cylinder - Area of circle

This gives

Surface area = 404 + 226.08 - 50.24

Evaluate

Surface area = 579.84

Hence, the surface area of the composite solid is 579.84 square feet
