Step-by-step explanation:

The required curved surface area =30.772 cm² and the total surface area = 1261.412 cm² for the cylinder.

The volume of a cylinder of radius 14cm is 210cm².
curved and total surface area to be determined.

The cylinder is defined as a 3D solid that keeps two identical bases joined by a curved surface, at a certain distance.

Here, Volume of cylinder(V) = 210 cm²

   V=πr2h

   h = V/πr2

   h = 210/π*14²

   h = 0.34105

Area of curved surface = 2πr*h
                                       =  2*3.14*14*0.34
                                       =  30.772 cm²

The total surface area of the cylinder,
A = 2πrh+2πr²
A = 2*π*14*0.34+2*π·*14²
A = 1261.412 cm²

Thus, The required curved surface area =30.772 cm² and the total surface area = 1261.412 cm² for the cylinder.

Answer:

[tex] \displaystyle V _{ \text{cuboid}} =280 {in}^{3} [/tex]

Step-by-step explanation:

We are given the area of the base and the measure of the height of a solid figure . We want to find the volume of the figure.

Notice that the area of the base of the figure is not a perfect square. Thus, we assume the solid figure to be a cuboid.

Cuboid is a three dimensional rectangle. The dimensions of cuboid are length, width and height

Remember that

[tex] \displaystyle V _{ \text{cuboid}} = l\times w \times h[/tex]

Since the base area (l×w) is 40in² and height (h) is 7in, simply substitute:

[tex] \displaystyle V _{ \text{cuboid}} =40 \times 7[/tex]

simplify multiplication:

[tex] \displaystyle V _{ \text{cuboid}} =280[/tex]

hence,

The volume of the figure is 280 in³

Answer:

28/11hr or about three hr

Step-by-step explanation

1/4+1/7=11/28

or 28/11 hr

Answer:

2 hours and 32.7 minutes. This is a good problem to become familiar with. It comes up in physics quite frequently.

Step-by-step explanation:

1 job/4 hours + 1 job / 7 hours = 1/x

1/4 + 1/7 = 1/x

(7 + 4)/28 = 1/x

11/28 = 1/x

x / 1 = 28/11

x = 2.54 hours repeating.

1 hour = 60 minutes

0.54 hours = x minutes

1/.54 = 60/x

x = 0.54 * 60

x = 32.7 minutes

Answer:

a_{n} = a_{1} + (n-1)d

a_n = the nᵗʰ term in the sequence

a_1 = the first term in the sequence

d = the common difference between terms

The general term of an arithmetic sequence can be written in terms of its first term a1, common difference d, and index n as follows: an=a1+(n−1)d. ... The nth partial sum of an arithmetic sequence can be calculated using the first and last terms as follows: Sn=n(a1+an)2.
