Answer:

1) 87.92 cm

2) 615.44cm

Step-by-step explanation:

Circumference (C) = 2π = πd (d=2r)

AREA (A) = πr^2

Use π = 3.14

1).Given that d=28cm, substitute the given value for diameter to the formula for circumference:

==> C= (3.14)(28) cm = 87.92cm

2).Given that d=28cm, substitute the given value of diameter to the formula for finding the RADIUS:

⇒ r = (½)(28) cm = 14cm

Then substitute the value of radius to the formula for area:

==> A = (3.14)(14)² cm = (3.14)(196) cm = 615.44cm

I hope it's help you...☺
