What is the area of a circle with a radius of 1 foot?

3.14 ft² or 2,917 cm²

Step-by-step explanation:

To do this, we need to know the expression to calculate the area of a circle.

The area of any circle is:

A = πr²

Where:

π: value of pi, which is 3.14

r: radius of the circle, in this case 1 ft

Calculating the area in units of ft:

A = 3.14 * (1)²

A = 3.14 ft²

Now, if you convert the foot to cm we have:

1 * 30.48 = 30.48 cm

Solvinf for A:

A = 3.14 * (30.48)²

A = 2,917.15 cm²

Pi feet squared

Step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
