Maths mate: using pie (3.14) 22/7 (fraction) calculate the circumference of the top of the stool (half of the top of the stool measures to be 21cm)

Hi Kaeruno,

The radius of the stool is 21 cm. To find the circumference, multiply this by 2 pi, since multiplying by 2 gives you the diameter and multiplying that by pi give the circumference.

2pi * 21cm

= pi * 2 * 21cm

= pi * 42cm

= (22/7) * 42cm

= 924/7 cm

= 132 cm.

The circumference is 132 cm.

If you have any further questions, feel free to message me!

Sincerely, taeuknam.

step-by-step explanation:

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
