A cone has a height of 8.4 centimeters and a base with a radius of 5.2 centimeters. what is the volume of the cone??

1 answer:

3 0

Cone Volume = (π • r² • h) ÷ 3


Cone Volume = (π • (5.2)² • 8.4) ÷ 3

Cone Volume = (3.14159 * 27.04 * 8.4) / 3 

Cone Volume = 237.85606208

Step-by-step explanation:

For cutting problems, we make the assumption that there is no loss of length due to the material moved or removed by cutting.

2 m = 200 cm

so there are ...

(200 cm)/(10 cm/section) = 20 sections

that can be cut from the pipe.

Given: circle k(O), ED diameter, m∠OEF=32°, m EF=(2x+10)°. Find: x

Snezhnost [94]

Answer:

The value of x is $53\°$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc DF

we know that

The inscribed angle measures half that of the arc comprising

$m$

we have

$m$

substitute

$32\°=\frac{1}{2}(arc\ DF)\\ arc\ DF=64\°$

step 2

Find the measure of x

we know that

$arc\ DF+arc\ EF=180\°$ ---> is a semi circle

we have

$arc\ DF=64\°\\ arc\ EF=(2x+10)\°$

substitute

$64\°+(2x+10)\°=180\°\\ 2x\°=180\°-74\°\\ 2x\°=106\°\\ x=53\°$
