Answer:

Area = 132.73

Perimeter/Circumference = 40.84

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.

Answer:

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
