Find the surface area of the sphere. use 3.14 for pie. round to the nearest tenth.

The answer is b) Use this formula: S. A (sphere)= 4 pi r ^ 2  (where

r = diameter/2= 7 yd

Step-by-step explanation:

S. A (sphere) = 4 pi r^2 = 4 (3.14) (7 x 7) = 615.4

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
