Answer:
2πr³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ← r is the radius and h the height
Here h = 2r, hence
V = πr² × 2r = 2πr³
Answer:
8√0.2
Step-by-step explanation:
using Pythagoras Therom
(68)^2 = (60)^2 + (x)^2
4624 = 3600 + x^2
4624/3600 = x^2
1.28 = x^2
√1.28 = x
x = 8√0.02
Answer:
choose the last option
Step-by-step explanation:
Given
g(a) = a² - 5a
f(a) = 4a - 4
Now
g(a) / f(a)
= (a² - 5a) /( 4a - 4)
Hope it will help :)
Answer:
a
b
Yes
Step-by-step explanation:
From the question we are told that
The probability that a random selected person of age 40 years or older is a jogger is
The probability that a random selected person of age 40 years or older is a male given that he/she jogs is
Generally the probability that a randomly selected person age 40 years or older is male and jogs
Generally it would be unusual because the probability that a randomly selected person age 40 years or older is male and jogs is greater than 0.05[border line for statistical significance]
