A circle with the diameter of 40 inches. what is the area?

Vsevolod [243]

Answer:

A= 1256

Step-by-step explanation:

The formula for area of a circle is $A=\pi r^{2}$

1. Diameter is DOUBLE of radius, so the diameter must be divided by 2. 40/2 = 20.

2. Then, plug in the values into the area formula. A= 3.14 $(20^{2})$

3. Solve. A= 1256. (Remember that 20 squared is 20x20)

Heather is going to graph y = -3x2 + 3. How is the parent graph transformed?

Yuki888 [10]

Any x² graph is a parabola. The negative in front is going to flip the parabola upside down to look like a camel hump. The 3 is going to make the graph narrower. The three at the end makes the y intercept 3. So the top of the graph will be shifted up to (0,3).
The answer would be A I believe

What’s the answer? And why

B; if P equals one they would ha. have to divided it by 10 so do that to 4.3 and you would get 0.43
