Find the circumference of the circle. Round your answer to the nearest centimeter.
A. 8cm
B. 16cm
C. 79cm
D. 157

b. 16

Step-by-step explanation:

Since you have the radius, you have to multiply that by two to get the diameter.

The formula for the circumference is d(pi) so you multiply the diameter times pi.

Then you round that answer, 15.7, to the nearest centimeter, which is 16

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .

yes

step-by-step explanation:

(2x+3)(x+5)(x-4)
