What is the surface area of the right cone below?
1 answer:
<h2>
</h2>
Total surface area of cone is 176π
<h3>Explanation:</h3>
Surface area of curved surface of a cone is give by π⋅r.l , where r is the radius and l is the slant height of the cone.
Hence surface area of curved surface of a cone is π×8×14=112π .
As surface area of base is π×82=64π .
Hence total surface area is 112π+64π=176π

Answer
Formula
where r is the radius of a circle.
As shown in the image
Diameter of the circle = 16 .3 cm
= 8.15 cm
Put in the formula
As
= 51.2 cm (approx)
Therefore the circumference of a circle is 51.2cm (approx) .
Option (D) is correct .
Answer:
16π
Step-by-step explanation:
Given:
<u>Formula:</u>
Replace the radius in the formula:
Evaluate the area:
Since the question says to determine the area in terms of π, the final answer is 16π.
