pls help me find the circumference and the area of a circle with radius 7m. (will mark brainliest) spammers reported.

Area = 154 m^2

Circumference = 44m

Step-by-step explanation:

We know, that circumference=

Given, Radius = 7m

So with the given information, we can find the circumference,

=> = C (C = Circumference)

=> 2 * 22/7 * 7

=> 2 * 22 (As 7 and 7 cancel each other out)

=> 44m

Therefore, cricumference = 44m

It's is also given it find area of the circle

Area = A =

=> = A

=> 22/7 * 7 * 7 (as 7 = radius)

=> 22 * 7 (as 7 and 7 cancel each other out)

=> 154m^2

Therefore, know we know the Area as well,

Area = 154 m^2

Circumference = 44m

Hope me answer helps :)

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
