Answer:
A=672 m²
Step-by-step explanation:
a²+b²=c² (to find h)
14²+b²=50²
196+b²=2,500
b²=2,304
√b²=√2,304
b=48
h=48
(base×height)÷2
(28×48)÷2
1,344÷2
A=672 m²
(i.) CA = πrl
CA = π (5*13)
CA = 65π
(ii.) TA = πrl + πr^2
TA = 65π + π (5^2)
TA = 65π + 25π
TA = 90π
(iii.) To get the height of the cone, you have to use the Pythagorean theorem. Plug in the radius for a and the slant height for c.
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169 Height = 12
b^2 = 144
b = 12
(iv.) v = (1/3)πr^2h
v = (1/3)π(5^2)*12
v = (1/3)π(25*12)
v = (1/3)π*300
v = 100π
Answer:
<h2><u><em>
x = -2.27272727273</em></u></h2><h2><u><em>
in fraction</em></u></h2><h2><u><em>
x = -25/11</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
Solve for X
6x+60x+150=0
66x = -150
x = -150 : 66
<u><em>x = -2.27272727273</em></u>
<u><em>in fraction</em></u>
<u><em>x = -25/11</em></u>
6600 BC because that is further in the past than 2500 BC
