Musya8 [376]3 years ago
7 0

Answer:

The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.

The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.

Step-by-step explanation:

<h3>The diameter can be solved using: D = \frac{C}{\pi }</h3>

So, the first step would be : D = \frac{20}{\pi }

Then : D = 20 ÷ \pi

Finally, the answer will be : 6.36619772 cm. or 6.4 cm.

<h3>The Radius can be Solved using: r = \frac{c}{2\pi }</h3>

The first step would be : r = \frac{20}{2\pi }

Then : 20 ÷ 6.2831853071796 (2\pi)

Finally, the answer will be : 3.18309886 cm. or 3.2 cm.

Multiply and simplify the product. 2i(4 – 5i) select the product. –2i 2i –10 8i 10 8i
Crazy boy [7]

The multiplication of the expressions 2i and (4 – 5i) is 10 + 8i. Then the correct option is D.

<h3>What is multiplication?</h3>

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The expressions are 2i and (4 – 5i).

Then the product of the expression will be given as

2i (4 – 5i)

8i – 10i²

And we know that i² = -1

Then we have

8i – 10 (–1)

10 + 8i

A cylinder has a base with a diameter of 10.8 cm and height 15 cm into the volume of a cylinder in a cubic centimeters round you
LekaFEV [45]

Answer:

V=1,373.44\ cm^3

Step-by-step explanation:

<u><em>The correct question is</em></u>

A cylinder has a base with a diameter of 10.8 centimeters and height 15 centimeters. Enter the volume of the cylinder, in cubic centimeters. Round your answer to the nearest hundredth

we know that

The volume of a cylinder is equal to

V=\pi r^{2} h

where

r=10.8/2=5.4\ cm ----> the radius is half the diameter

h=15\ cm

assume

\pi =3.14

substitute

V=(3.14)(5.4)^{2} (15)=1,373.44\ cm^3

Find the volume of the cylinder with a diameter of 12 inches and a height of 10
kati45 [8]

Answer:

360 pi in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the diameter is 12 so the radius is 1/2  the diameter

r = d/2 = 12/2 = 6

V = pi (6)^2 * 10

V = pi (36)*10

V = 360 pi in ^3

We can approximate pi by 3.14

V =1130.4 in ^3

Or we can approximate pi by using the pi button

V =1130.973355  in ^3

The local hardware store wants to increase their inventory. last year 15 electric screwdrivers cost them $300. at the same cost,
VMariaS [17]

Answer:

Cost of 45 screwdrivers will be = $900

Step-by-step explanation:

Last year 15 electric screwdrivers cost to the local hardware store = $300

So per screwdriver cost = \frac{\text{Total cost}}{\text{Total number of screw drivers}}

= \frac{300}{15}

= $20

Now we have to calculate the cost of 45 screw drivers.

Since cost of 1 screwdriver = $20

So cost of 45 screwdrivers = 20×45 = $900
