On 2 questions 1. pie plates can be measured by the length of their radius. determine the size pie plate needed for a pie with a circumference of about 159.72 cm 2. pizza stone can be measured by the length of their diameter. determine the size pizza stone needed for a pizza with a circumference of about 75.36 cm

1. To find this answe you use the formula for finding the circumference.

C= pi x d, where d is the diameter.

159.72 = 3.14d, then solve for d by dividing both sides by 3.14.

d=50.87

The radius is half the diameter, so 50.87/2.

The answer is approximately a 25 cm pie plate.

2. Use the same formula as above:
75.36 = 3.14d, and solve for d.
d= 24 cm
You will need a 24 cm pizza stone.

The answer would be -3.9> -4.5

I’m not sure what it is i sorry : ((
