Answer:
64π m³
Step-by-step explanation:
The general formula for the volume of a cylinder:
V = πr²h, where 'r' is the radius and 'h' is the height
In the given problem, the radius is equal to 4 m and the height is equal to 4 m. Plugging these values into the equation:
V = π4²(4) = π16*4 = 64π m³
Answer:
The final balance is £20,489.21.
The total compound interest is £10,489.21
Step-by-step explanation:
pretty sure you know the answer after you round this
Let the smaller number be x
let the larger number be y
According to Question-
x + y = 2y - 4
→ x - y = -4 ...1
if larger number is decreased by 1/3 we get equation -
x + y/3 = -20
→ 3x + y = -60 ...2
adding equation 1 and 2, we get:
4x = -64
→ x = -16
→ y = -60 - 3(-16)
→ y = -60 + 48
→ y = -12
Answer:
E. 0.1401
Step-by-step explanation:
The mean here has been given as 20.9
The standard deviation sd = 4.7
Random sample n = 32
Sd/√n
= 4.7/√32
= 0.8309
Probability of x less than 20
= 20-20.9/0.8309
= -0.9/0.8309
= -1.083
P(z<-1.083)
When we go to the z table
= 0.1401
Therefore the probability is 0.1401 and the answer to this question is E.
