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:
Step-by-step explanation:
surface area = 2πrL + 2πr² = 14πL + 98π
14πL + 98π = 880
14πL = 880-98π
L = (880-98π)/(14π) ≅ 55.9 cm
Answer:
=N+8
Step-by-step explanation:
You would remove the parenthesis
Add the numbers together
and the n would = 8
Answer:
correct answer is : To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
