Since we are finding area, we divide the circumstance by 2 to get the radius which is held to the power of 2, we then multiply the radius that is being held to the power of 2 by 3.14. Your answer should end up being 45.3416.

Answer:

181.46 = A

Step-by-step explanation:

pi X r^2 is the area of a circle

the diameter is already given so you can skip the radius an jump straight into pi X d diameter = (r^2) giving you area pi X diameter

Professor quantum has two coins which total 35 cents. since one of the coins is not a dime, what are the two coins
Brums [2.3K]

So, there are 1, 5, 10, 25 and 50 cent coins.

The most logical combination would be a dime and a quarter (10 + 25 = 35) but it is said that "one of the coins is not a dime".

But, there is something many people don't notice. It says that one of the coins isn't a dime, but the other one can be a dime. So, the two coins are a quarter and a dime.


Hope it helped,

What is the image of the point (8,4) after a rotation of 90° counterclockwise about the origin?<br>​
Alenkinab [10]
<h3>Answer:  (-4, 8)</h3>

=========================================================

Explanation:

The 90 degree counterclockwise rotation rule we use is

(x,y) \to (-y,x)

the x and y coordinates swap places, and we change the sign of the first coordinate after the swap.

After using that rotation rule, we would go from (8,4) to (-4, 8) which is the final answer.

----------------

Extra info (optional section):

Define the following three points

A = (0,0)

B = (8,4)

C = (-4,8)

Use the slope formula to find that AB and AC have slopes of 1/2 and -2 in that order.

Those slopes multiply to -1, since (1/2)*(-2) = -1. This is a property of any two perpendicular lines as long as neither line is vertical and neither is horizontal. So this is sufficient to prove that the lines are perpendicular. This further means that a 90 degree rotation has taken place.
