Answer:
And since we know the surface area 326.7 in^2 we can solve for the value of r like this:
And replacing we got:
And the best answer would be:
5.1 in
Step-by-step explanation:
For this case we need to use the formula for the surface area of a sphere given by:
And since we know the surface area 326.7 in^2 we can solve for the value of r like this:
And replacing we got:
And the best answer would be:
5.1 in
Methods for solving a system of equations:
- elimination
- substitution
- augmented matrix
Ranks of method ( number one being the most preferred method)
1) elimination
2) substitution
3) augmented matrix
Elimination is my preferred method because it is simple and easy to work out and hard to get wrong.
Augmented matrix is my least preferred method because it is easy to get wrong and it requires complex steps to solve a simple equation.
Hope this helps ;)
Answer:
-21
Step-by-step explanation:
put in -3 where x is
-3^2 9
-9-12 = -21
Miles driven in 8.07 gallons = 241 miles
Miles driven in 1 gallons = (241/8.07) * 1
= 29.86 miles
