The formula for finding the surface area of a sphere is A=4π

. Since we already have the radius, we just plug that into the equation, like so:
A = 4 x 3.14 x 
First, following the rules of PEMDAS, do the exponent, coming out with an answer of 1. Now, multiply 4 x 3.14, which is 12.56. 12.56 x 1 = 12.56.
Rounded to the nearest tenth, your answer is
12.6.

Answer:
Step-by-step explanation:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
When you add the right side of the equation, you get 33.2, because they are the same problem but on side has brackets.
Hope this helps you.
Answer: C
m = slope
m = (y2 - y1) / (x2 - x1)
2 points:
(2, -4) x1 = 2 and y1 = -4
(0, 4) x2 = 0 and y2 = 4
m = (4 - (-4)) / (0- 2)
m = 8 / -2
m = -4
Equation of the line is : y = mx + b
So we got...
y = -4x + b
Then we can use any of the two points given to solve for b. I’m going to use (0, 4).
y = -4x + b
4 = -4(0) + b
4 = 0 + b
4 = b
Therefore the equation of the line is
y = -4x + 4
