Area and Perimeter of a circle with a diameter of 13 cm?

Step-by-step explanation:

P = (3.14) (d) diameter divided by 2 equals radius

P = (3.14) (13)

P=40.82

A = (3.14) (6.5) (6.5)

A = (3.14) (42.25)

A=132.665

Area = 132.73

Perimeter/Circumference = 40.84

Step-by-step explanation:

Formula for calculation Area with Diameter - (π/4) x D^2

Formula for calculation Circumference with Diameter - 2π

D = Diameter

π = Pi or 3.14 ...

We would round all numbers to the nearest hundredth if they have one.
