Big cone:
1/3 * Pi * 6^2 * 16
= 192 Pi

small cone :
1/3 * Pi * 3^2 * 8
=24 Pi

Big cone - small cone:
=192 Pi - 24 Pi = 168 Pi
=168 Pi = 527.7875658

volume of small cone = 24 pi /75.39822368
volume of the frustrum = 168 Pi / 527.7875658

HELP ME PLZZZZ!!!!!!!!!!!!!!!!!!

Alekssandra [29.7K]

the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the radius will be 3

slant height is

$\sqrt{r^2+h^2}$

h is 4.7 and r is 3

$\sqrt{3^2+4.71^2} \\5.58427$

slant height is 5.58427

lateral surface area

$\pi r\sqrt{h^2+r^2}$

$\pi (3)\sqrt{4.71^2+3^2} \\52.63053$

lateral surface area is 52.63053

total surface area

$\pi r(r+\sqrt{h^2+r^2})$

$\pi 3(3+\sqrt{4.71^2+3^2})$

$80.90486$

total surface area is 80.90486

F=1.8C+32 solve for given variable

liq [111]

Answer:

Step-by-step explanation:

The formula F = 1.8C + 32 can be used to find the temperature in degrees Fahrenheit F when the temperature is given in degrees Celsius C. For what value is the temperature in degrees Fahrenheit equal to the temperature in degrees Celsius? Justify your reasoning by writing and solving an equation. (Hint: If Fahrenheit and Celsius are equal, they can be assigned the same variable.)
