The formula of the circumference of a circle is:
C = 2 * π * r
Since r is not given, I will use all choices to find the radius. Whatever circumference corresponds to the correct radius of the problem, then it is the correct one.
a) 22.0 cm = 2 * 3.14 * r ⇒ r = 22.0 cm / 6.28 ⇒ r = 3.50 cm
b) 69.1 cm = 2 * 3.14 * r ⇒ r = 69.1 cm / 6.28 ⇒ r = 11.00 cm
c) 34.5 cm = 2 * 3.14 * r ⇒ r = 34.5 cm / 6.28 ⇒ r = 5.49 cm
d) 17.3 cm = 2 * 3.14 * r ⇒ r = 17.3 cm / 6.28 ⇒ r = 2.75 cm
Answer:
According to the data, Mr. Brown is likely to win the election.
Step-by-step explanation:
56-35= 21, So 35 is Mr. Brown's voters and 21 did not vote for him. 35 is greater than 21. Also 35 is over half of 56 which is 28 so <u>he is likely to win.</u>

Answer:
Step-by-step explanation:
When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:
2(x +3) = 30 . . . . an equation for the given conditions
__
We can solve this equation by dividing by 2:
x + 3 = 15
x = 12 . . . . . . subtract 3
The number is 12.
