Answer:
B. 60cm
Step-by-step explanation:
The area of parallelogram is calculated by multiplying b × h (b: base, h: height)
the base given here is 5 cm and height is 12 cm
5×12 = 60
That would be the rounded answer
Answer:
Assuming the cones are the same height, then
V1 = pi * r^2 * h/3 = 3.14159*1^2*h/3
V2 = 3.14159*2.5^2*h/3 = 3.14159*6.25*h/3
V1/V2=(3.14159*h/3)/(3.14159*6.25)*h/3
V1/V2 = 1/6.25 = .16
V2/V1=(3.14159*6.25)*h/3/(3.14159*h/3)
V2/V1=6.25/1 = 6.25
Alright, lets get started.
The amount of investment means principal : 42000
rate of interest : r : 4 % compounded annually
time of deposit t = 5 years
The formula for amount : A
A = P(1 + r/n)^nt
As interest is compounded annually, means n = 1
A = 42000 ( 1 + 4/100)^5
A = 42000 (1 + 0.04)^5
A = 42000 (1.04)^5
A = 42000 * 1.21665290
A = 51099.42 $
So the balance of Ila's account after 5 years will be 51099.42 $ : Answer
Hope it will help :)
