Find the area of a circle with a radius of 3

28.27

Step-by-step explanation: first multiply the radius by itself 3 times 3 = 9

then take 9 and multiply it by 3.14 which is 28.27

Step-by-step explanation:

So to find the area of a circle, you have to use this formula:

A = 3.14r^2

So just plug everything in like this:

A = 3.14 * 3^2

Then solve

A = 3.14 * 9

Area is = 28.26 units^2

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
