8x + 26 = 98
8x = 72
x = 9
8x + 26 + z = 180
8(9) + 26 + z = 180
72 + 26 + z = 180
98 + z = 180
z = 82
Hey there!!
Volume of a cone : πr²h/3
Where, πr²h is the volume of a cylinder.
Hence,
V cone = V cylinder / 3
Hence,
The above mentioned formula is wrong/false.
Hope my answer help!!
Answer:
h=-12
Step-by-step explanation:
h/6-1=-3
add 0ne to -3 since it's the opposite of -1
h/6=-2
multiply by 6/1 since it's the opposite of 1/6
h=-12
Answer:
a = 9.849
b = 20.25
c = 491.03
Step-by-step explanation:
By using Pythagoras theorem in the right triangle BDC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
BC² = BD² + DC²
a² = 9² + 4²
a = 
a = 
a = 9.8489
a ≈ 9.849 units
By mean proportional theorem,

AD × DC = BD²
b × 4 = 9²
b = 
b = 20.25 units
BY Pythagoras theorem in ΔADB,
AB² = AD² + BD²
c² = b² + 9²
c² = (20.25)² + 9²
c² = 410.0625 + 81
c = 491.0625
c = 491. 063 units
