Answer:
803.84, or C.
Step-by-step explanation:
If we know the circumference then we can use that to find the radius!
-
(π =pi)
Area of a circle formula: π · r^2
-
Let us plug in the circumference into the formula (not the area formula, the circumference one!)
c=2πr
100.48=2πr - 2*3.14 =6.28
100.48=6.28r
divide both sides by 6.28!
r= 16
Now, we plug that in the area formula.
π · r^2
3.14 * 16^2
3.14 * 256 =
803.84
Answer:
the answer I say would be correct would be D
You just slide the decimal 2 places over so it would be 0.22
Answer:
Step-by-step explanation:
The surface area of a rectangular prism can be calculated with the following formula:
Where "l" is the length of the rectangular prism, "w" is the width and "h" is the height.
In this case you can say that the length, the width and the heigth of this rectangular prism, are the following:
Knowing these values, you can substitute them into the formula shown before:
Finally, you must evaluate in order to calculate the surface area of the rectangular prism.
You get that this is:
