Circumference is equal to diameter multiplied by pi. C=d X pi. To find the radius we need to rearrange this equation. We know what pi and the circumference are, so to find diameter we do circumference divided by pi. D=c/pi. 942/pi = 299.85. This gives us the diameter, for the radius simply divide by 2 which is 149.92 :)
Answer: 94.5
Step-by-step explanation:
9/2 × 21/4
Get common denominator
9 × 2 =18
2 × 2 = 4
18/4 × 21/4
21 × 18 = 378
378/4 = 94.5
Answer:
5
Step-by-step explaimation:
Let's say x is the number we are trying to find.
9 = 3*(x-2)
9 = 3x -6
3x = 15, x = 5

Answer:
Length of crab in x years = x + 2
Step-by-step explanation:
Since the crab grows 1 inch per year, and it would grow:
1 inch in the 1st year
2 inches in the 2nd year
3 inches in the 3rd year
4 inches in the 4th year
.
.
.
And so on.
However, in order to find the total length, you need to remember that the crab is originally 2-inches long. So the total length after x years would be the number of inches it grew over the years (x) + the length before the growth (2).
Thus, Length of crab in x years = x + 2
5x + 10y = 800
y = 50
10y = 10*50 = 500
800 - 500 = 300
300/5 = 60
x = 60
5(60) + 10(50) = 800
60 small vehicles were washed in total
