Answer:

3.14 square inches or π square inches

Step-by-step explanation:

The radius of a circle is 1 inch. What is the area?

r=1 in

The formula for the area of a circle is given as:

πr²

The radius (r) = 1 inch

Hence,

Area of the circle = π × 1²

= 3.1415926536 square inches

Approximately = 3.14 square inches or we can say that the Area of the circle = π square inches

Give an example of a polynomial that is a perfect square. How do you know that it is a perfect square? Give its factored form.
lora16 [44]

Answer:

Step-by-step explanation:

A polynomial is a  perfect square if has the form:

a^2+2ab+b^2

Its factored form is  (a+b)^2.

We can obtain examples by taking any value of a and b.

For example:

a=x  anb  b=2y.  

Thus we obtain a polynomial that is a perfect square:

x^2+2(x)(2y)+(2y)^2=x^2+4xy+4y^2

Solve the equation below for x.<br> сх — 4 = 7
RoseWind [281]

Answer:

x = 11/c

Step-by-step explanation:

To solve this equation for x, we simply need to apply equation operations and isolate the x variable.

cx - 4 = 7

cx - 4 + 4 = 7 + 4

cx = 7 + 4

cx = 11

cx * (1/c) = 11 * (1/c)

x = 11 * (1/c)

x = 11/c

Cheers.
