What is the circumference of a circle with a radius of 5 in terms of π choices: a: 5 π square units b: 25 π square units c: 50 π square units d: 10 π square units

10 π square units

Step-by-step explanation:

The circumference of a circle is given as 2πr

where π = pie

r = radius

Since radius has been given as 5

Circumference= 2πr

= 2 × π × 5

= 10 π units

answer: the equation matches the regression

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
