The angle measures are 60, 60, 60
Answer:
x=5
Step-by-step explanation:
(x^2)-25=0
(x^2)=25
√(x^2)=√25
x=√25
x=5
Youre missing the x for 6.5
Answer:
Correct option: B -> 36
Step-by-step explanation:
The surface area of a circular cone is given by the formula:
Surface area = pi * radius * (radius + slant height)
If the inicial radius is 4 in and the slant height is 9 in, we have:
Surface area = pi * 4 * (4 + 9) = 52pi in2
The radius and the slant height are multiplied by 6, so we have:
radius = 6 * 4 = 24 in
slant height = 6 * 9 = 54 in
So the new surface area is:
New surface area = pi * 24 * (24 + 54) = 1872pi in2
The factor of the surface areas is:
New surface area / Surface area = 1872pi / 52pi = 36
Correct option: B
R + t = 42
r = 25
Plug in 25 for r
(25) + t = 42
Isolate the t by subtracting 25 from both sides
t + 25 (-25) = 42 (-25)
t = 42 -25
t = 17
Hope this helps
