<h3>Answer:   66.48</h3>

=============================================================

Explanation:

The formula we'll use to find the surface area is:

SA = 4*pi*r^2

In this case, the radius is r = 2.3 meters

SA = 4*pi*r^2

SA = 4*pi*(2.3)^2

SA = 66.47610054996

SA = 66.48 square m

You'll type the expression you see for step 2 into your calculator to get the result of step 3. The result is approximate. Let your calculator handle the decimal digits of pi as your teacher instructs. The last step is us rounding to two decimal places. The units for the surface area are in square meters, because we can effectively unwrap the outer surface (think of it like unwrapping a present) to lay it out flat.

#2 Find the slope given the points (6,-12) and (15,-3)*
castortr0y [4]

Greetings :)

To find slope of two points we will need to use this equation:   \frac{y^2-y^1}{x^2-x^1}

 x^1     x^2     y^1    y^2  

( 6 , -12 ) ( 15 , -3 )

Now let's replace the equation with the numbers. (it will be a fraction).

\frac{-3-(-12)}{15-12}         =         \frac{9}{9}

The equation equals 9 over 9, which also equals 1.

The slope of the line is 1.

Explain two ways you could solve 20 = 5(−3 + x
emmasim [6.3K]

Answer:

7 is x

Step-by-step explanation:

1) Divide both sides by 5 to give

4=-3+x

x=4+3

x=7

2) Multiply 5 with the RHS (Right Hand Side) to give

20=-15+5x

20+15=5x

35=5x

x=7
