Answer:
<h2> 8in</h2>
Step-by-step explanation:
the given formula in the question is not correct
here is the correct formula
S. A. =2πr^2 +2πrh
given that S.A=207.24
radius r= 3in
207.24=2*3.142*(3)^2 +2*3.142*(3)h
207.24=56.556 +18.852h
207.24-56.556=18.852h
150.684=18.852h
h=150.684/18.852
h=7.99
Approximately the height is 8in
Answer:
16 ft
Step-by-step explanation:
Based on the situation above, it forms into a right triangle. Therefore we can apply the Pythagorean Theorem. We will use the formula below:
c = √( a² + b²)
In the problem above, the ladder acts as the hypotenuse denoted by c. It has a length of 20 ft. While the base denoted by b is 12 ft. Therefore, we need to solve for a. We will derive the formula above.
c² = a² + b²
a² = c² - b²
a = √( c² - b² )
a = √( 20² - 12² )
a = 16
The unit is in ft.
