Answer:
x=39°
Step-by-step explanation:
the tangent from the diameter is 90°
x+90+51=180 sum of interior angle of the triangle is 180
x=180-90-51=39°
Answer:
h = 3 cm
Step-by-step explanation:
Given that,
Diameter, d = 6 cm
Radius, r = 3 cm
Volume of the cone, V = 28.26 cm³
The formula for the volume of a cone is given by :
So, the height of the cone is equal to 3 cm.
The answer is 7^12
This is because since they both have the same base, you just have to subtract the powers.
A^2+B^2=C^2
160^2+120^2=c^2
25600+14400=c^2
40000=C^2
square root(40000=c^2)
diagonal is 200m
100^2+b^2=200^2
10000+b^2=40000
b^2=30000
square root(b^2=30000)
Unknown side is 173.2m
120×160×.5= 9600 m^2
this is bottom triangles area
100×173.2×.5=8650 m^2
this is the top triangle area
8650+9600= 18,250 m^2
total area
