Answer:
452.39 square units
Step-by-step explanation:
a = πr²
π(12)^2
144π = 452.389
Answer:
We know it's at -1260 feet and descends 5 per minute
The expression of this would be: -1260 - 5x, where x would be the time in minutes, as from -1260 feets it descends 5 per min.
Then, if we need to calculate it when it passes 12 minutes, we can replace the x by 12, and get the distance it would be
-1260 -5*12 = -1320 feet
And the answer would be -1320 feets
x^2 - 5 this will be the equation formed.
<h3>What is exponents?</h3>
An exponent is the number of times a number is multiplied by itself. For example, 2 to the third (written as 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of one is itself.
<h3>Calculation </h3>
let the number be x
x^2 - 5 this will be the equation formed
