Answer:
The value of y would be 45.5
Step-by-step explanation:
To solve this problem, start with the base form of direct variation.
y = kx
Now we can use our original values to model the equation and find k.
35 = k(2.5)
14 = k
Now we can model the equation as:
y = 14x
Now to find y, when x = 3.25, simply put 3.25 into the equation.
y = 14(3.25)
y = 45.5

Answer:
13.) 0.19625 15.) 37.68
Step-by-step explanation:
Formula for area of a circle: A=πr²
13.) 3.14 x .25² = 0.19625
Formula for circumference for a circle: C=πD or C=2πr
15.) (6 x 2) x 3.14 = 37.68
