Find the area of the circle d=10 in 62.80 in^2 ,15.70^2, 314.00in ^2, 78.50in^2, 31.40 in2

Step-by-step explanation:

In order to find the area, we need to find the radius. In order to find the radius, we need to divide 10 by 2 because the radius is half of the diameter.

10 ÷ 2 = 5

So, the area of the circle (given that the diameter is 10) is 78.50 in².

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

y=sec x is the correct answer
