Answer:
1.77 ft.^2
Step-by-step explanation:
<u>What we know:</u> diameter of circle is 1.5
<u>What we need:</u> the radius to find the area of a circle
<u>What we can do</u>: 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
<u>What we need to know:</u> Formula of finding Area of Circle is A=(pie)r^2
<u>Insert what we know:</u> A=(pie).75^2
<u>Work out problem(do radius to the second power first)#1:</u> .75^2 = .5625(unrounded)
<u>Work out problem(multiply number by pie))#2:</u> .5625 multiplied by (pie) = 1.7671458676442586966352369030947
<u>Round Answer to </u><em><u>nearest hundredth</u></em><u>: </u> 1.77 ft.
<u></u>
<em><u>Note:</u></em> 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
