The answer is 9cm
SA = r + r 2
452.16 m 2 = (3.14)(6 m)(x) + (3.14)(6 m) 2
452.16 m 2 = (3.14)(6 m)(x) + (3.14)(36 m 2)
452.16 m 2 = (18.84 m)x + 113.04 m 2
339.12 m 2 = (18.84 m)x
18 m = x
Answer:
V = 678.24cubic cm
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of a cylinder
π - pie
r - radius of a cylinder
h - height of a cylinder
Given:
π - 3.14
h - 6
d = 12
d = 2r
Divide both sides by 2
d/2 = 2r/2
d/2 = r
r = d/2
r = 12/2
r = 6
Insert the values into the formula
V = πr^2h
V = 3.14 * 6^2 * 6
= 3.14 * 36 * 6
= 678.24cubic cm
Answer: 2(x + 5) less than 3x
Step-by-step explanation: 2 = twice the... x + 5 = the sum of a number and 5 (number = x) 3x = three times the number
