The surface area formula is 4 x pi x r^2
Answer:
write the equation of the line that passes through (7,6) and (-1,2) in a slope intercept form.
The formula for a diagonal of a rectangle is <span>√w^2+h^2, with w and h being the width and height. Plug in your numbers to get </span><span>√7^2+5.5^2. Simplify that into </span><span>√49+30.25, then to </span><span>√79.25. Use your calculator to get 8.9022. The diagonal is 8.9 feet.</span>
18/22 = 2*9/2*11 = 9/11
Therefore, your answer is 18
