(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:
Critical points are 1 and -1
Maximum at x=1
Minimum at x=-1
Step-by-step explanation:
We are given that a function
on ()
We have to find the critical points of the function.
To find the critical point we will differentiate function w.r.t x and then substitute f'(x)=0
Therefore, the critical points of the given function are 1 and -1.
When we goes from 0 to 2 then the sign of derivative change from positive to negative .Therefore, function has local maximum at x=1.
When we goes form -2 to 0 then the sign of derivative change from negative to positive .Hence , function has local minimum at x=-1
Hence, critical points are local maximum and local minimum .
Its 7,200 since 7,159 has a 5 before the 1. Anything above 5 rounds up anything below will round down.
Answer:
50 degree
Step-by-step explanation:
the angle sum property of the equilateral triangle is =180 degree
since, 52 degree +78 degree +x =180 degree
130 degree + x =180 degree
x= (180-130) degree
<h3> x= 50 degree</h3>
