Find The Area Of The Circle To The Nearest Tenth Use 314 For Π class=

Sagot :

Answer:

Step-by-step explanation:

Use the formula for area of a circle

A = [tex]\pi r^{2}[/tex]

The diameter is 8ft, if there was only a line from the middle to the edge of the circle, then it would be radius

The radius is half the diameter so divide 8 by two and you get the radius

Plug in the radius into the formula

A = [tex](4ft)^{2} \pi[/tex]

the parenthesis indicate you aren't only squaring the ft, but also the 4

4ft * 4ft = 16[tex]ft^{2}[/tex]

(remember you are also multiplying the unit, in this case feet)

A = [tex]16ft^{2} \pi[/tex]

there aren't parenthesis here, meaning you aren't squaring the 16

A = 50.24[tex]ft^{2}[/tex]
