Answer:

452.39 units²

Step-by-step explanation:

To get the surface area of a sphere, all you need is the radius. The formula for the surface area is:

V=4πr²

So all you need to do is plug in the values:

V = 4πr²

V = (4)(π)(6)²

V = 4π36

V = 452.39 units²

<u>BUT WAIT! If your teacher set the value of π to 3.14, the answer would be 452.16 units².</u>

Answer:

452.16 units^2

Step-by-step explanation:

Given

Radius = r= 6 units

The formula for finding the surface area of a sphere is:

A = 4\pi r^2\\A= 4 * 3.14 * (6)^2\\A=12.56*36\\A = 452.16

In the formula, π is taken as 3.14.

So, the surface area of the given sphere is 452.16 units^2 ..

My daughter is having a hard time trying to figure this problem.
Natalija [7]

Hey there! :-)

First, let's find the slope of the line.

We can do that by using this formula:

Slope=Rise/Run

Where

Rise=how many units we move up

Run=how many units we move left or right.

We move 5 units up and 8 units to the right.

Therefore, the slope is 5/8.

The y-intercept (where the line touches the graph) is -9/8.=

Therefore, the equation of the line is y=5/8x-9/8.

Hope this helps you daughter. Use the comment section to clarify any doubts.
