Which is the closest approximation to the area of the circle? Use 3.14 or 22/7 to approximate π.

Which Is The Closest Approximation To The Area Of The Circle Use 314 Or 227 To Approximate Π class=

Sagot :

For a circle, A=[tex] \pi [/tex] [tex] r^{2} [/tex]
For this circle the radius is 18mm so when we plug it in we get A=[tex] \pi (18)^{2} [/tex]
[tex] 18^{2} = 324 [/tex] so now we have A=324[tex] \pi [/tex]
Using 3.14 as [tex] \pi [/tex] We now have A=(3.14)(324) which is equal to 1017.36
So we know that A=1017.36 [tex] mm^{2} [/tex]

area=pi times r^2

radius=18mm
pemdas
exponents first
18^2=324
pi aprox=3.14
324 times 3.14=1017.36 mm^2 or square mm
