Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is T

soldier1979 [14.2K]

Scientific Notation is the way of writing a number or expressing them in a shorter or more compact way.

No, Taylor's resoning is incorrect because 2,800,000 = $2.8 * 10^{6}$

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is $2.8 * 10^{6}$ .

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, Taylor's reasoning is incorrect.

A cylinder has a height of 12 feet and a radius of 5 feet. What is its volume? Use ≈ 3.14 and round your answer to the nearest

beks73 [17]

Answer: The volume is 942 cubic feet , 942 ft^3

Step-by-step explanation:

The formula for the volume of a cylinder is v = pi* r^2 * h

Where v is the volume, r is the radius and h is the height.

Input the values for pi, radius, and the height into the formula to solve for the volume.

v = 3.14* (5^2) * 12

V = 3.14* 25 * 12

V = 942
