Answer:
V candle ≈ 196.9 cm³
Step-by-step explanation:
Volume of cone = ( π·r²·h)/3
V candle = V big cone -V small cone
V candle = [ π·4²·(8+5) - π·2²·5]/3
V candle = ( π·16·13 - π·4·5)/3
V candle = (π·16·13 - π·4·5)/3
V candle = π·(208 - 20)/3
V candle = π·188/3
V candle = 196.8731396
V candle ≈ 196.9 cm³
Answer:
x=13
Step-by-step explanation:
we can guess that the three angles are a linear pair and equal 180
in this case we can start writing a equation
x+105+62=180
now we can subtract both whole numbers from 180 but that takes longer, so we will combine the whole numbers on the left side.
x+167=180
now we can go ahead and subtract 167 from both sides. by doing so, it isolates the x and gives you your answer
180-167=13
so... x=13
If the radius is the radius of the inscribed circle then the side of the triangle = radius * 6 / (sq root(3))side = 20.785tan 60 = height / half-sideheight = tan 60 * half-sideheight = 1.732 * 10.3925 height = 17.99981 triangle area = .5*side*heighttriangle area = 10.3925 * 17.99981triangle area = 187.06
If the radius is the radius of the circumscribed circle then the side of the triangle = radius *3 / (sq root(3))side of the triangle = 6 * 3 / sq root(3)side of the triangle = 10.3923048454 half-side = 5.1961524227 height = tan 60 * half-sideheight = 1.732 * 5.196height = 8.9997
triangle area = .5*side*heighttriangle area = 5.196 * 8.9997triangle area = 46.764
Hope this helps!
