Answer:The simple interest rate is 7.50%
Step-by-step explanation:
Simple interest, I =( P × T × R) / 100
Where P= Principal investment
T = Time in years
R = rate
Given
P= 981.60
I = 1000 - 981.60 = 18 .40
T = 13 weeks = 13 / 52 = 0.25 year
I =( P × T × R) / 100
Cross multiply
I × 100 = P × T × R
18.40 × 100 = 981.60 × 0.25 × R
1840 = 245.4 R
R= 1840 / 245.4
R = 7.498%
To the nearest tenth
R = 7.50%
6 : 24 x : 20 Cross multiply.
Answer:
3.5325
Step-by-step explanation:
V = 3.14*(.75^2)(2)
You divide the diameter by 2 to get the radius which is 1.5/2 =.75
r=.75
h=2
and you use the equation for volume of cylinder which is V = pi x radius squared x height
