Fiona draws a circle with a diameter of 14 meters. what is the area of fiona’s circle? 7 14 28 49

49pi

Step-by-step explanation:

d

work:

use this formula to find the area: A=πr²

to find "r" you need to fin the radius, so find half of the diameter.

14/2 = 7

so, you have a radius of 7.

now, plug that into your equation.

A=π(7)²

so, we have A=49π.

out of your options, D is the best answer since you would have an answer over 150 if you multipled by pi. :)

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
