Answer:
733 inches
Step-by-step explanation:
V= 3.14*5^2*28/3
Order of Operations (PEMDAS)
5^2=25
25*3.14= 78.5
78.5*28= 2198
2198/3=732.66
Round to nearest cubic inch

Answer:
Kindly check explanation
Step-by-step explanation:
The hypothesis :
H0 : μ = 3000
H0 : μ ≠ 3000
The test statistic :
(xbar - μ) ÷ (s/√(n))
xbar = 3500
μ = 3000
σ = 300
n = 30
(3500 - 3000) ÷ (350/√(30))
Test statistic = 7.824
Df = 30 - 1 = 29
Tcritical at 0.01 = 2.462
Test statistic > critical value ; we reject H0 ; and concluded that there is significant evidence that
μ ≠ 3000
Answer:
s/2πh =r
Step-by-step explanation:
s=2πrh
Divide both sides by 2πh to isolate r
s/2πh =2πrh /2πh
s/2πh =r
