What is the area of the two-dimensional cross section that is parallel to the base of the cylinder, rounded to the hundredths place?
Use. 3.14 for the value of pi.
The radius is 5.2 m
if a circle of radius r then pi r^2
To find the area of a two-dimensional cross section of a cylinder parallel to its base, we can use the formula for finding the area of a circle. The formula for the area of a circle is A = πr^2, where A represents the area and r represents the radius.
In this case, the radius of the cross section is given as 5.2 m, and the value of pi (π) is given as 3.14. Plugging these values into the formula, we get:
A = 3.14 * (5.2)^2
To calculate the area, we square the radius by multiplying it by itself:
A = 3.14 * 27.04
Now we multiply the value of pi (3.14) by 27.04:
A = 84.8736
Rounding the result to the hundredths place gives us the final answer:
A ≈ 84.87 square meters
