Find the circumference and the area of a circle with diameter 2 m .

The answer to your question is Circumference = 12.56 m, Area = 3.14 m²

Step-by-step explanation:

Data

Circumference = ?

Area = ?

diameter = 2 m

Process

1.- Calculate the radius

radius = diameter / 2

-Substitution

radius = 2/2

-result

radius = 1 m

2.- Calculate the circumference

Circumference = 2πr

π = 3.14

Circumference = 2(3.14)(2)

                         = 12.56 m

3.- Calculate the area of the circle

Area = πr²

-Substitution

Area = (3.14)(1)²

-Simplification

Area = (3.14)(1)

-Result

Area = 3.14 m²

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
