It is 4 square cm hopefully that help with part of the question
We use proportion in this problem solving.
We know that 100% = 40.00 and 125%=x
I take 125% because the marks the price up 25%. So it is 100%+25%.
100x=40.00×125
x=40.00×125÷100
x=50.00
So the she sells the cell phone at 50.00
Answer:
56
Step-by-step explanation:
Because the angle is past the 55 mark by one and 55 + 1 is 56.
Answer:
729π ft³
Step-by-step explanation:
Applying,
Volume of a cone
V = πr²h/3.............. Equation 1
Where r = radius of the base, h = height, π = pie
From the question,
Given: r = 9 ft, h = 27 ft
Substitite these values into equation 1
V = π(9²)(27)/3
V = 729π ft³
Hence the volume of the figure in terms of π is 729π ft³
