Find the circumference and area of the circle. Use 3.14 or 22/7 for π.

Hoochie [10]

Answer:

circumference: 62.8 ft
area: 314 ft²

Step-by-step explanation:

The circumference is given by the formula ...

C = πd

Using the given numbers, the circumference is ...

C = (3.14)(20 ft) = 62.8 ft

The area is given by the formula ...

A = πr² . . . . . where radius r is half the diameter

Using the given numbers, the area is ...

A = 3.14(10 ft)² = 314 ft²

Factor the polynomial completely

aliina [53]

We have $2x^2-8$ .

First let us factor the 2 to obtain,

$2(x^2-4)$

We can now see clearly that the expression inside the parentheses is a difference of two squares.

We now write the 4 as 2². So that we obtain the expression,

$2(x^2-2^2)$

Recall that

$a^2-b^2=(a+b)(a-b)$

Hence our expression becomes,

$2(x+2)(x-2)$

Therefore, when factored completely,

$2x^2-8=2(x+2)(x-2)$
