Step-by-step explanation:
I don't know If this is the answer you wanted but please tell me If I'm right or wrong.
You can use the cosine rule for this - you might have to change some of the letters around for it to make sense though. Hope this helps!
Answer:
y = -7
Step-by-step explanation:
y2 - y1 / x2 - x1
-7 - (-7) / -2 - (-3)
0/1
= 0
y = 0x + b
-7 = 0(-2) + b
-7 = 0 + b
-7 = b
Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr ×
( r is the radius )
given arc = 63.48π , then
2πr ×
= 63.48π ( cancel 2π on numerator/ denominator )
r ×
π = 63.48π ( divide both sides by π )
= 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm
