Keep the base and add the powers.
25^(1/2)= 5
Answer:
194.78 yards
Step-by-step explanation:
Diameter: d=62yards
Perimeter: p=2×pi×r=pi×d, where d=2×r, r being the radius.
We get: p=pi×d=62×pi=194.78 yards
Answer:
$2347; $46,940 from deposits and $5060 from interest
Step-by-step explanation:
In this question, we are asked to calculate the 3 things. The amount deposited per month, how much of total deposits comes from the total $52,000 and the total amount coming from interest.
To proceed, we first calculate the regular payment. Afterwards we calculate the deposit to get the amount coming from the $52,000 total deposit.
Using the formula interest = Annuity - Total deposit , we get the value of the interest.

The number of feet in the length of the handrail is 17.3 ft.
The easiest way to see this is to imagine that we can "unfold" the spiral to create a rectangle
The bottom side of the rectangle is just the arc length of a circle with a radius of 3 ft turned through 270°= (3/4) of a whole revolution
(3/4) (2pi) (3) = (9/2)pi ft = 4.5 pi ft
The side of the rectangle will be the rise of the staircase = 10ft
And the diagonal of the rectangle will be the length of the handrail
We can use the Pythagorean Theorem to solve this
Handrail length = √ [ (4.5 pi)^2 + 10^2 ] ≈ 17.3 ft
Pythagorean theorem is the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
