Help plz:)))I’ll mark u Brainliest

Explanation:

The formula we'll use to find the surface area is:

SA = 4*pi*r^2

In this case, the radius is r = 2.3 meters

SA = 4*pi*r^2

SA = 4*pi*(2.3)^2

SA = 66.47610054996

SA = 66.48 square m

You'll type the expression you see for step 2 into your calculator to get the result of step 3. The result is approximate. Let your calculator handle the decimal digits of pi as your teacher instructs. The last step is us rounding to two decimal places. The units for the surface area are in square meters, because we can effectively unwrap the outer surface (think of it like unwrapping a present) to lay it out flat.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
