Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm
Answer: see work
Step-by-step explanation:
Total area is 24x22=528
one circle area is (pi)3^2=9(pi)
that times 4 because of 4 circles =36(pi)
so the total are minus the circles now
in terms of pi the answer is 528-36(pi)
if pi = 3.14 the answer in 414.96
Step-by-step explanation:
13? i forgot all this math XD
First one, x = 90
second one, x = 10, 5x = 50, 2x = 20
