Find the area of the circle R=3ft

28.27 ft²

Step-by-step explanation:

Area of the circle is equal to πr².

Where r is the radius.

π(3)²

9π = 28.274334

The area of the circle is 28.27 ft² approximately.

see below

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

A = pi (3)^2

A = 9pi

Letting pi be approximated by 3.14

A = 9 * 3.14

A=28.26 ft^2

If we use the pi button

A = 28.27433388 ft^2

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
