Answer:
1. 6pi or 18.84cm
2. 20pi or 62.8cm
3. 13pi or 40.82cm
4. 9.5pi or 29.83cm
5. You calculate the circumference of a circle with the expression 2pi(r). r stands for the radius. You can also use pi(d), or pi x diameter.
7. You would use 2pi(r) to find the circumference of a circle when given the value of the circle's radius.
8. You would use pi(d) to find the circumference of a circle when given the value of the circle's diameter.
Answer:
n = 73
Step-by-step explanation:
<h2>—Math</h2>
8² = x ==> x = 64
x + 12 = y ==> y = 64 + 12 = 76
y – 3 = n ==> n = 76 – 3 = 73

2e = 4e - 16
*subtract 4e from both sides
-2e = -16
*divide both sides by -2
<u><em>e = 8</em></u>
Answer:
70
Step-by-step explanation:
30 + 40 = 70
That means
4 times (4 times ) the sum (the quantity x+y to be named) of (times ) 14+26 (14+26)
4 times (14+26)
