Answer:

Circumference of the circle is $131.88m$

Step-by-step explanation:

we have to find the circumference of the given circle.

Given:

Diameter=42 m

$\\diameter=2*radius\\42 =2*radius\\radius=42/2\\radius=21 m$

Circumference of a circle= $2\pi r$

$=2*\pi *21\\=2*3.14*21\\=42*3.14\\=131.88$

So, the circumference of the circle is $131.88m$

Please help me with this question please!!!

A = x * x = x^2

B = 6 * x = 6x

C = 8 * x = 8x

D = 6 * 8 = 48

So the area of the whole shape is each side added up then multiplied to give (x+6)(x+8) =

x^2 + 14x + 48
