A circle has a circumference of 100 yd. Find its area.

Step-by-step explanation:

In order to find the area of the circle we must first find it's radius using the circumference

Circumference of a circle = 2πr

where

r is the radius

From the question

Circumference = 100 yd

So we have

100 = 2πr

Divide both sides by 2π

We have

We have

radius = 15.9 yd

Since we've found the radius we can use it to find the area

Area of circle = πr²

Area = (15.9)²π

Area = 252.81

= 794.226

We have the final answer as

Area = 794.23 yd² to 2 decimal places

Hope this helps you

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
