Hint:
Diameter(d)= 2 radius(r)
circumference= 2πr= πd
1. diameter= 19 × 2 = 38 inches
circumference= 3.18(38) = 119 inches (3 s.f.)
Note that I use 3.18 instead of π because the question states to use 3.14 for π.
Likewise, if you are given the diameter, divide it by 2 to find radius. Let's try a question which only gives you the diameter.
4. radius= 22 ÷ 2 = 11cm
circumference= 3.14(22) = 69.1cm (3 s.f.)
<h2>4(-8x + 5) - (-33x - 26) =</h2><h2>-32x + 20 + 33x + 26= (distributive)</h2><h2>-32x + 33x + 26 + 20= (combine like terms)</h2><h2> x + 46</h2>
Hope it helps.
6m+1=-23. Do the inverse operation of adding 1 which is to subtract 1 to both sides =====> 6m+1-1= -23-1
You divide by 6 both sides
6m/6=-24/6
m= -4

The answer is "Math".....but technically the official name for it is Mathematics.
