Find the volume of a right circular cone that has a height of 17.5 m and a base with a circumference of 19.4 m

Answer: Volume = 174.71 cubic meters

Step-by-step explanation:

Hi, to answer this, first, we have to apply the formula for the circumference (C) of a circle.

C= 2πr

Substituting with c=19.4 in the formula, and solving for the radius (r)

19.4= 2πr

19.4/ 2π =r

r= 3.09

Finally we apply the formula:

Volume of a right circular cone: 1/3 π r^2 h

Where h is the height of the cone and r is the radius of the base.

Replacing with the values given and calculated:

V=1/3 π (3.09)^2 (17.5)

V = 174.71 cubic meters

Rock-music sales represented 24.8% of the total music sales in 2000. By 2007, rock-music sales represented 32.4% of the total mu

baherus [9]

Answer:

Unit Rate of Change = 1.27%

Step-by-step explanation:

In 2000, t=1 and Total Music sales = 24.8%

In 2007, t=7 and Total Music sales = 32.4%

The Slope $m=\dfrac{32.4-24.8}{7-1} =\dfrac{7.6}{6}=1.27\%$

The Unit Rate of Change is 1.27% and it means that the Total Music Sales Increased by approximately 1.27% every year.

Answer: 4/5 of a box of candy

Step-by-step explanation:

Justine sold 1¹/₅ times the ²/₃ of a box of candy that Grayson sold.

Justin sold;

= 1¹/₅ * ²/₃

= 6/5 * 2/3

= 12/15

= 4/5 of a box of candy

) What would the value of c be when

jasenka [17]

The value of c is 233.3

Step-by-step explanation:

Given equation is:

$\frac{18}{20}c-250=-40$

To find the value of c, we have to isolate c on one side of the equation

So,

Adding 250 on both sides

$\frac{18}{20}c-250+250=-40+250\\\frac{18}{20}c=210$

Multiplying by 20 on both sides

$20*\frac{18}{20}c=210*20\\18c=4200$

Dividing both sides by 18

$\frac{18c}{18}=\frac{4200}{18}\\c=233.3333$

Rounding off to the nearest one decimal place

c=233.3

The value of c is 233.3
