What is the surface area of the cone? Express your answer in terms of π.

Answers

Answer:

surface area of a cone = 132.935πft

Step-by-step explanation:

to find the surface area of a cone

given that

radius = 5ft

height of cone = 21ft

recall that the formulae for finding the surface area of a cone = πr( r + √ h² + r²)

so,

surface area of a cone = πr( r + √ h² + r²)

surface area of a cone = π x 5( 5 + √ 21² + 5²)

surface area of a cone = 5π ( 5 + √ 441 + 25)

surface area of a cone = 5π( 5 + 21.587)

surface area of a cone = 5π (26.587)

surface area of a cone = 132.935πft

Answer:

If you want just the area of the circle (the surface area) then it is 78.5

Step-by-step explanation:

Let that number be n.  Then:

     n            6

Through cross-multiplication we get:

(-15/56)*6 = -5n, which reduces to:

area of circle is πr²

area of semicircle is πr²/2

diameter=18

radius= 18/2=9

πr²/2 = (22/7* 9*9) / 2

2y-8-5y-40=0   (combine like terms)

Someone look at the photo and answer I need help

Answers

Step-by-step explanation:

To find the composite function, it says

[tex](f \: o \: g)(x)[/tex]

means we put the function g(x) into f(x) so that means it looks like

[tex]( \sqrt{x}) {}^{2} - 4[/tex]

Which equal

[tex]x - 4[/tex]

So that expression above is the answer.

To find the range we must find the range of the inner function ,(g(x) and then see which parts it corresponds of f(x).

The range of a g(x) which is a radical function is all real numbers.

The range of a f(x) which is a quadratic function is all real numbers greater than or equal to -4.

This means for our function to work we can use any numbers as long as it greater than -4.

So we would represent that as x is all real numbers as long as x is greater than or equal to -4

In interval notation this would be

[-4,+ infintiy)

The length of an arc AB from the given circle with radius 6in is 15.7in

Length of an arc

The formula for calculating the length of an arc is expressed as:

L = r theta

where

r is the radius = 6in

theta is the central angle = 150 degrees = 5/6π rad

Substitute

L = 6(5/6π)

L = 5π

L = 5(3.14)

L = 15.7in

Hence the length of an arc AB from the given circle with radius 6in is 15.7in
