A circle has a diameter of 6, an area of b square units, and a circumference of c units. What is the value of b + c ?

Step-by-step explanation:

Diameter = 6 units

Radius = Diameter/2 = 6/2 = 3 units

Taking π=3.14

Circumference = 2(π)(r) = 2(3.14)(3) = 6(3.14) = 18.84 = c

c = 18.84

Area = π(r)^2 = π(3)^2 = 9π =9(3.14) = 28.26 = b

b = 28.26

So,

b + c = 28.26 + 18.84 = 47.1

b=6π the unit(cm)

c=18.84 the unit(cm)

b+c=

9+18.84=27.84

Step-by-step explanation:

circumference=c

diameter=d

radius=r

area=b

d=2r

6=2r

6=r

2

r=3

b=πr^2

b=3×3π

=9π

c=2πr

=2(3.14)3

= 3.14×6

=18.84

ok
