Question

Find the exact area of the circle with the given radius.

r = 4.5 m



A.


4.5π m²


B.


9π m²


C.


20.25π m²


D.


81π m²

Answer 1

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

Answer 2

A = (pi)r^2 = (pi)4.5^2 = 20.25(pi)m^2 (C)

Answer 3

this is the equation to find Area... and here r is the radius.... in ur question u got 4.5 m as the radius...

Answer 4

yeah ok but i answered his question

Answer 5

\[A = \ \pi \ (4.5)^{2}\]\[A = \pi \ 20.25 m^{2}\]

Answer 6

Find the exact area of the circle with the given diameter.

d = 2.2 m



A.


1.21π m²


B.


2.2π m²


C.


4.4π m²


D.


4.84π m²

Answer 7

\[radius = \frac{ diameter }{ 2 }\]

Answer 8

u can find the radius using the above method... then plug the value f the radius to the equation..
\[A = \ \pi \ r^{2}\]
