Answer:

Approximately 157.08 sq. cm.


Step-by-step explanation:

The Area of an Ellipse is given by the formula  A=\pi a b

Here 2a = 10, so a = 5

Also, 2b = 20, b = 10


<em>Substituting these into the area formula gives us:</em>

A=\pi a b\\A=\pi (5)(10)\\A=50\pi\\A=157.08

The Area is <em>approximately</em> 157.08 sq. cm.

Which of the following changes in the price index produces the greatest rate of inflation: 106 to 112, 112 to 118, or 118 to 124
boyakko [2]

Answer:

A

Step-by-step explanation:

firstly you have to find the rate of change of the various price index in percentage.

A, From 106 to 112:

we find the difference 112-106 = 6

then the rate of change = 6/106 * 100 = 5.66%.

B ,From 112 to 118:

we find the difference 118-112 = 6

then the rate of change = 6/118 * 100 = 5.36%.

C ,From 118 to 124:

we find the difference 124-118 = 6

then the rate of change = 6/124 * 100 = 5.08%.

we can see that the price index with the greatest percentage is A.
