Answer:
88.2 squared
Step-by-step explanation:
The formula to find the area of a circle is <em>a = pi * r ^2</em>
Let's replace the values that we know.
a = 3.14 x 5.3 ^2
First, we should do 5.3 ^2, which is 28.09.
a = 3.14 x 28.09
Now we are able to do 3.14 x 28.09 which is 88.2026
But that isn't it! We need to round to the nearest tenth, which is this digit:
88.<u>2</u>026
Since next to the 2 there is a 0, you take out all the numbers after that 2. Which leaves you with:
88.2
The answer would be y=1/3x +4
Answer is A
100 - (5+d)×2
That's what my teacher told me.
Answer:
Step-by-step explanation:
The radius, r of the expanding circle of oil is modeled by the function:
, where s is time in seconds.
When s=5
Radius 
Area of a circle 
Therefore, the area of the oil spill when s=5 seconds
The area of the spill when s=5 seconds is 45pi square inches.
