Volume of the Cylindrical bar, V = pi * r^2 * h
V = pi * 200^2 * 9
V = 22/7 * 40000 * 9
Let's assume the radius of the sphere as r
Volume of the sphere V1 = 4/3 * pi * r^3
V1 = V
V1 = 4/3 * pi * r^3
22/7 * 40000 * 9 = 4/3 * 22/7 * r^3
r^3 = (40000 * 9) * 3/4
r^3 = 10000 * 9 * 3
r = ( 10 * 10^3 * 3^3)^(1/3)
r = 10^(1/3) * 10 * 3
r = 2.154 * 30
r = 64.63 cm
Answer:
y = 32
Step-by-step explanation:
(2y + 3) + 23 + 90 = 180
2y = 64
y = 32

Answer:
x = 22
Step-by-step explanation:
All the sides are equal. So, it is and equilateral triangle and so all the angles will be equal.
Each angle of equilateral angle = 180/3 = 60
3x - 6 = 60 {Add 6 to both sides}
3x = 60 +6
3x = 66 {Divide both sides by 3}
x = 66/3
x = 22
