Answer: Circumference of cake board is 35π cm.
Step-by-step explanation:Since we have given that
Diameter of a round cake = 30 cm
Diameter of a cake board is 5 cm longer than the diameter of a round cake.
So, Diameter of a cake board = 30+5=35 cm
So, radius of a cake board will be
As we know the formula for " Circumference of Circle ":
So, According to question, we get,
Hence, Circumference of cake board is 35π cm.
The answers to the questions
Answer:
9 meter.
Step-by-step explanation: 4 1/2 meters is too short, he would have to buy 2 lengths. 4 1/2 meters is 450 cm while 9 meters is 900 cm, if he gets the 900 cm length he can just cut off the excess to use later.
4c* 312n= x
you would have to find out how many people times the number of how much it is per person would equal the total of how much it would cost for them to be there
The compound equality is -1/2 because that is the center value of the problem
