Find the exact area of a circle with diameter of 10 units.

10pi
100pi
5pi
25pi

D.

Step-by-step explanation:

We have been given that diameter of a circle is 20 units.

To find the area of our given circle we will use area of circle formula.

, where r represents radius of circle.

let us find the radius of our given circle by dividing diameter by 2 as diameter is 2 times radius.

Upon substituting r=5 in area of circle formula we will get,

Therefore,the exact area of our given circle is square units and option D is the correct choice.

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
