Answer:

1.77 ft.^2

Explanation:

What we know: diameter of circle is 1.5

What we need: the radius to find the area of a circle

What we can do: Divide 1.5 by two to get the radius(since the diameter is twice the radius : radius x 2 = diameter)

Math --> 1.5 divide by 2 = .75

What we need to know: Formula of finding Area of Circle is A=(pie)r^2

Insert what we know: A=(pie).75^2

Work out problem(do radius to the second power first)#1: .75^2 = .5625(unrounded)

Work out problem(multiply number by pie))#2: .5625 multiplied by (pie) = 1.7671458676442586966352369030947‬

Round Answer to nearest hundredth: 1.77 ft.

Note: I use the pie sign for this problem. So I used : 3.1415926535897932384626433832795‬

I used a scientific calculator for the calculations.

^2 is added after the unit to show Area.

To the second power is multiplying the number by itself. Example: 4^2 = 16 = 4 x 4
