Consider this composite figure made of a cone and a cylinder. A cone has a height of 8 centimeters and radius of 3 centimeters.
dangina [55]

The volume of cone is 75.4 cubic centimeters and the volume of cylinder is 197.92 cubic centimeters. The volume of composite figure is 273.32 cubic centimeters.

Step-by-step explanation:

The given is,

                Composite figure made of a cone and a cylinder.

                A cone has a height of 8 centimeters and radius of 3 centimeters.

                A cylinder has a height of 7 centimeters and radius of 3 centimeters.

Step:1

              Volume of composite figure = Volume of Cone +

                                                                 Volume of cylinder............(1)

Step:2

            Formula for volume of cone,

                   Volume of cone, V_{cone} = \pi r^{2} \frac{h}{3}....................(2)

           Where, r - Radius of cone

                       h - Height of cone

           From the given,

                            r = 3 centimeters

                           h = 8 centimeters

           Equation (2) becomes,

                                                   = \pi (3^{2} )(\frac{8}{3})

                                                   =\pi (9)(2.667)

                                                   = (3.14 × 9 × 2.667)           (∵ \pi = 3.1415)

                                                   = 75.4

                Volume of cone, V_{cone} = 75.4 cubic centimeters

Step:3

           Formula for volume of cylinder,

                   Volume of cone, V_{cone} = \pi r^{2} h....................(2)

           Where, r - Radius of cylinder

                       h - Height of cylinder

           From the given,

                            r = 3 centimeters

                           h = 7 centimeters

           Equation (2) becomes,

                                                   = \pi (3^{2} )(7)

                                                   =\pi (9)(7)

                                                   = (3.14 × 9 × 7)           (∵ \pi = 3.1415)

                                                   = 197.92

                Volume of cylinder, V_{cylinder} = 197.92 cubic centimeters

Step:4

         Equation (1) becomes,

            Volume of composite figure = 75.4 + 197.92

                                                            = 273.32 cubic centimeters    

Result:

           The volume of cone is 75.4 cubic centimeters and the volume of cylinder is 197.92 cubic centimeters. The volume of composite figure is 273.32 cubic centimeters.

A 12-foot ladder rests against the side of a house. The base of the ladder is 3 feet away from the side of the house. How high a
Triss [41]

Answer:

3.root 15 feet

Step-by-step explanation:

To solve this problem, we will use Pythagorean’s theorem. Now let’s visualize a right angled triangle in which the hypotenuse stands for the total ladder length and the base of the ladder standing away from the wall is say the adjacent.

The length of the ladder is the opposite which is the last side of the complete triangle.

Hence, to find this side we use s^2 = 12^2 - 3^2

S^2 = 144 -9

S^2 = 135

S= square root of 135 = 3.root15 feet

I don't know how to do this practice problem :/
Veseljchak [2.6K]

First of all, we know that Emily travels 3/4 of a mile in 4 minutes and 30 seconds (i.e. 9/2 of a minute). So, her current velocity is

v = \dfrac{\frac{3}{4}}{\frac{9}{2}} =\dfrac{3}{4}\cdot\dfrac{2}{9} = \dfrac{1}{6} of a mile per minute.

At this speed, it takes

t = \dfrac{s}{v} = \dfrac{3.42}{\frac{1}{6}} = 3.42\cdot 6 = 20.52

minutes to travel 3.42 miles.

Since she left at 8.25, she will arrive at about 8.46, so she's on time for school.
