Answer:
3.6 cm or 36mm
Step-by-step explanation:
So we know that there are 10 millimetres in a centimetre. So we can convert the 18cm into millimetres to make it easy to subtract
18cm*10=180mm
now take the pencil length subtracted by the length of the pen.
180mm-144mm=36mm
now if you want the answer in cm, convert it by dividing the answer by 10
36/10=3.6cm

So the question wants to calculate the change of the area among the circles in respect to its radius changes and the best answer would be the following:
A. 50.27 to 78.54
B.50.27 to 63.62
C.50.27 to 52. 81
The rate of change are the following:
A. 56.24%
B. 26.56%
C. 5.05%
We have two right triangles and three different rectangles.
The formula of an area of a right triangle:

l₁, l₂ - legs
We have l₁ = 20cm and l₂ = 21cm. Substitute:

The formula of an area of a rectangle:

l - length
w - width
We have:
rectangle #1: l = 22cm, w = 29cm

rectangle #2: l = 22cm, w = 21cm

rectangle #3: l = 22cm, w = 20cm
