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:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
