Answer:

Step-by-step explanation:

Radius = diameter ÷ 2

Diameter = distance between C and D

<em><u>Find the distance using distance formula</u></em>

<em><u /></em>Diameter, CD = \sqrt{(-7-1)^2 + (-4-2)^2}  = \sqrt{8^2 + 6^2} = \sqrt{100} = 10 \ units\\\\Therefore , radius = \frac{Diameter }{2} = 5 \ units<em><u /></em>

Find the volume of the cone. Round your answer to the nearest tenth if necessary. Use 3.14 for it.
Korolek [52]

Answer:

452.448cm^3

Step-by-step explanation:

Given data

Height= 25cm

Diamter= 12cm

Radius= 6cm

The expression for the volume of a cone is given as

V= 1/3*πr^2h

Substitute

V= 1/3*3.142*6^2*25

V=  1/3*3.142*36*12

V=  1/3*1357.344

V=452.448cm^3

Hence the volume is 452.448cm^3

The height of a stack of 12 pennies is 18.24 millimeters. What is the thickness of each penny.
Helga [31]
I’m not great at math so I could easily be wrong, but

I divided the 18.24 millimeters by 12 pennies and got 1.52

So if the pennies are all the same size, each penny should 1.52 millimeters.

To show work:

18.24/12=1.52
