Answer:

\Huge\boxed{131.88}

Step-by-step explanation:

Hello There!

First thing we want to do is find the formula for circumference of a circle

C = 2(3.14)r

where r = radius

we are given the diameter so we have to convert that into radius to do so we just divide by 2

42/2=21 so the radius equals 21 inches

now we just plug in 21 for r in the formula

C = 2(3.14)21\\2*3.14=6.28\\6.28*21=131.88\\C=131.88

So we can conclude that the circumference of the circle is 131.88 inches

How do we calculate 25% of 300
Natali5045456 [20]
25% is equal to \frac{1}{4}. To get 25% of 300, we multiply 300 by either 0.25 or \frac{1}{4}. This gives us (300)( \frac{1}{4}) =  \frac{300}{4}  =  \frac{150}{2} = 75

What is 8x-4y=-12;-3,-1,1 solve for y
polet [3.4K]
8x - 4y = -12
4y = 8x + 12
y = 8/4 x + 12/4
y = 2x + 3

When x = -3,
y = 2(-3) + 3 = -6 + 3 = -3
When x = -1,
y = 2(-1) + 3 = -2 + 3 = 1
When x = 1,
y = 2(1) + 3 = 2 + 3 = 5
