Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2

Answer:
Surface area of the cone =352 feet²
Step-by-step explanation:
To calculate the surface area of a cone, we will use the formula;
Surface area of a cone = πr² +πrl
where r denotes the radius of the cone and l denotes the slant height of the cone.
From the question given
radius r =7 slant height l=9 and π =22/7
we can now proceed to insert the variables into the formula and then solve
Surface area of a cone = πr² +πrl
=22/7 × 7² + 22/7 × 7×9
= 22/7 × 49 + 22/7 × 63
=154 + 198
=352 feet²
Surface area of the cone =352 feet²
