We have to find the number of significant figures in the product of 1.6 cm and 2.4 cm.
Let us first find the product of 1.6 cm and 2.4 cm.
= 3.84 square cm.
Now, we have to determine the number of significant figures in 3.84
The significant digits of a number are the digits have meaning or they contribute to the value of the number. All non-zero digits are significant
, any zeros between significant digits are also significant figures and the trailing zeros to the right of a decimal point are significant figures.
Therefore, in 3.84, there are 3 significant figures in this number.
So, there are 3 significant figures in the product of 1.6 cm and 2.4 cm.
Volume of cylinder = (pi)r^2 • h
So with the numbers, it’s:
V = (3.14)12.5^2 • 30
V = (3.14)156.25 • 30
V = 490.625 • 30
V is about 14,718.75
Since I rounded, the answer for your problem is “about 17,671 cubic feet.”
Hope this helped!

Just divide 384 by the other number

F(x) = -(x+7)² + 4
f(x) = -(x+7)(x+7) + 4
f(x) = -(x² + 7x + 7x + 49) + 4
f(x) = -x² - 14x - 49 + 4
f(x) = -x² - 14x - 45
True for f(x)
