Area of a circle is:

A = pi * r^2

If the diameter is 10 feet, the radius will be half of that or 5.

So:

A = 3.14 * 5^2

Simplify exponent:

A = 3.14 * 25

Multiply:

A = 78.5

The area is πr².
The radius r is half the diameter. The diameter is 10 ft so the radius is 5 ft.

A=\pi \times 5^2=25 \pi

The area is 25π ft².

If the interest rate on a savings account is 0.02%, approximately how much money do you need to keep in this account for 1 year

At first glance, this problem might be overwhelming so try approaching it slowly by doing these steps:

Step 1: Start by understanding what the problem is really asking.
You might notice that the problem is just a percentage problem, with a twist! If you still don't see it, the problem is just asking what the base should be given a percentage and the amount.

Step 2: Recall the concepts relevant to the question.
We can identify a single formula that will be important in getting the answer:
base*percent=amount

Step 3: Apply the concept to the context of the problem.
You'll see that we already have the percent from the interest rate which is 0.02% and the amount from the below-minimum-balance fee which is $9.99.

There goes the little twist: you have to manipulate the equation to get the base. Dividing both sides of the equation by the percent we'll have:
base= \frac{amount}{percent}

Step 4: Evaluate to get the answer to the problem.
We simply substitute the given numbers and evaluate.
base= \frac{percent}{amount}= \frac{9.99}{0.0002} =49,950

Answer: You need $49,950 in the account to cover the Below-Minimum-Balance Fee from your interest.

The total distance to be covered was 52 miles. If he cycled at a constant rate of 13 miles per hour, how much time did Ricky tak
QveST [7]
13 miles per hour means he will cover 13 miles in 1 hour.

therefore in 2 hours, 26 miles.    3 hours, 39 miles.  4 hours, 52 miles.

Or time = distance/speed

time = 52/13 = 4 hours

Gemma recently rode her bicycle to visit her friend who lives 6 miles away. On her way there, her average speed was 16 miles per
DochEvi [55]

first speed --- x mph

return speed -- x+16 mph

6/x + 6/(x+16) = 1

times each term by x(x+16)

6(x+16) + 6x = x(x+16)

x^2 + 4x - 96 = 0

(x-8)(x+12) = 0

x = 8 or x is a negative

her first speed was 8 mph

her return speed was 24 mph

check:

6/8 + 6/24 = 1 , that's good!

Sorry I did it wrong

So what I did was take

1/10 to the fifth power 

Which would equal .00001
