Assuming that the units are in cm
Given,
Diameter of the cone = 12 cm
Using the above, the radius of the cone can be determined, which is half the diameter of the cone
∴ Radius of the cone (r) = 12/2 = 6 cm
Height of the cone (h) = 7 cm
Using the above, slant height (s) = √(r² + h²) = √(6² + 7²) = √36 + 49 = √85 = 9.22 cm
π = 3.14
Now using the above values, we can calculate the total surface area of the cone.
Total surface area of the cone (A) = Lateral surface area of the cone (L) + Base surface area of the cone (B)
Lateral surface area of the cone (L) = π r s = 3.14 x 6 x 9.22 = 173.70 cm²
Base surface area of the cone (B) = π r² = 3.14 x 6² = 113.04 cm²
Total surface area of the cone = L + B = 173.70 + 113.04 = 286.74 cm²

<h2>Question</h2>
What is Quadrilateral!?
<h2>Answer</h2>
a quadrilateral can be defined as a closed, two-dimensional shape that has four straight sides. ✔
Step-by-step explanation:
<h3>
Here are examples of Quadrilaterals</h3>
The seven types of quadrilaterals are parallelogram, rhombus, kite, rectangle, trapezoid, square, and isosceles trapezoid. ✔
<h3>Properties</h3>
<em>The sides do not have to be the same length. Quadrilaterals have four sides, four vertices, and four interior angles that add up to 360</em>°✔
Therefore, I hope this helps! ツ
