Their answer is correct so you need explanation?
Answer:
314 =4 Pi (r squrared)
Step-by-step explanation:
so second option is the right answer
First 42/78% to get 1% then multiply the number by 100% to get around 53 11/13
For direct variation y varies directly with x, then we use equation y = kx
Where k is the constant of proportionality
Given: Y equals 2 when X equals 3
We plug in 3 for x and 2 for y and solve for k
y = kx
2 = k(3)
Divide both sides by 3

Now we plug in 2/3 for k

Given x=-0.5 and find out y

y=-0.33
the value of y is -0.33 when x=-0.5
I think the answer is more than
