A scientist measures the diameter of a drop of water that is shaped like a sphere. It diameter is 0.2 centimeter. What is the approximate surface area of the drop of water? Use 3.14 for r and round to nearest hundredth of a square
centimeter.
O 0.03 cm?
O 0.13 cm?
O0.50 cm?
O 2.51 cm?

The correct answer is B. 0.13 cm^2

Step-by-step explanation:

Correct on EDG.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
