Answer:
the height of the cone is 24 inches.
Step-by-step explanation:
formula to find height is h = √(s^2 - r^2), where h is the height, s is the slant height, and r is the radius.
The simple interest on x dollars at 5-percent annual rate for 2 year is $0.1x
<h3>Calculating simple interest</h3>
The formula for calculating the simple interest is expressed as:
SI = PRT
where
P is the principal = $x
R is the rate = 5%= 0.05
Time T = 2 years
Substitute
SI = x * 0.05 * 2
SI. = 0.1x
Hence the simple interest on x dollars at 5-percent annual rate for 2 year is $0.1x

Answer: 12πins.
Step-by-step explanation:
Since the area if a circle = πr²
From the question
Area of the circle = 36πins²
To find the circumference of the circle, we need to find the common radius of the circle and this could be achieved from the area of the circle given above.
πr² = 36π, solving this gives. Divide through by π
r² = 36
r = +/-√36
= +/-6
Now to find the circumference of the circle, we substitute for r in the formula below.
Circumstances = 2πr
= 2 ×π × 6
= 12πins.
