Find the distance round the semi circle with a diameter of
35 cm

a semi circle is half a circle so 35 divided by 2 is 17.5

Step-by-step explanation:

54.91 cm ² is the perimeter

formula =2 × 3.14× r (half the diameter)× 0.5

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
