Asked by MArio

how do u find the area and circumference of a circle if the radius is 2.5 ?
Answered by Ms. Sue
Area = Pi * r^2
A = 3.14 * 2.5^2
A = ?

Circumference = 2 * Pi * r
C = 2 * 3.14 * 2.5
C = ?


Answered by Guido
Ms. Sue gave you the formulas.

Did you apply the formulas?

A = 3.14 (r)^2

A = 3.14 (2.5)^2

A = 3.14 (6.25)

A = 19.625

==================

C = 2 (3.14)(2.5)

C = 15.7
