The distance around the middle of a sphere (the circumference) equals 37.699 in. what is the surface area of the sphere?
podryga [215]

To solve this problem you must apply the proccedure shown below:

1. Clear the radius from the formula for the circumference of a circle and substitute values, as following:

C=2\pi r\\ r=C/2\pi \\ r=37.699in/2\pi \\ r=5.99in

2. Substitute the radius calculated into the formula for calculate the surface area of the sphere:

SA=4\pi r^{2} \\ SA=4\pi(5.99in^{2})\\ SA=450.88in^{2}

The answer is: 450.88in^{2}

PLEASE HELP! I know the top part I just need the bottom!
Zolol [24]

slope  = (y2-y1)/(x2-x1)

        = (70-52)/(8-1)

    = 18/7

=2.6

point slope form

y-y1 = m(x-x1)

y-52 = 2.6(x-1)

distribute

y-52 = 2.6x-2.6

add 52 to each side

y = 2.6x+49.4

y = 2.6x +49


the initial temperature is 49.4 or about 49

and it increases about 2.6 degrees each week

How are the solutions to the following two equations related m+5=72 <br> m+72=5
EastWind [94]
To see how they are related, let us solve the two equations.

FIRST EQUATION

m + 5 = 72

\rightarrow \: m = 72 - 5

\rightarrow \: m = 67

SECOND EQUATION

m + 72 = 5

\rightarrow \: m = 5 - 72

\rightarrow \: m = - 67

Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
