Answer:

The Circumference of the circle is #15.7 cm# and Area is #19.625 cm#

Explanation:

We know that,

Circumference of Circle #= 2pir#

and

Area of Circle #= pir^2#

The radius here is 2.5 cm because radius is the half of diameter. The value of #pi# is 3.14

Now,

Circumference of Circle:

#= 2*3.14*2.5#

#= 6.28*2.5#

#= 15.7 cm#

Area of Circle:

# = 3.14*(2.5)^2 #

# = 3.14 * 6.25 #

# = 19.625 cm #
