Answer:
78.5
Step-by-step explanation:
the formula is C = 2π r
we know the diameter is 24
half of the diameter is radius
24 divided by 2 is 12
substitute what we know
C=2 times 3.14 times 12= 75.36
The closest option is 78.5

What percent of 55 is 13
percent means parts out of 100
x%=x/100
'of' means multiply
what percent of 55 is 13 means
x/100 times 55=13
times both sides by 100
55x=1300
divide both sides by 55
x=23.63636363636363
answer is 23.63%
Slope is -3/5x in this equation
