what is this?
Step-by-step explanation:
Well first you have to find the unit rate, or how many "p" each pencil costs. So you take 54 and divide it by 6, and you get 9. So each pencil costs 9 p, so you take 9 and multiply it by 8. That gets you 72, so 8 pencils cost 72p.
Answer:
10) 95π/6 ft
12) 39π/4 ft
Step-by-step explanation:
10) 2π * 19 * 150/360 = 95π/6 ft
12) 2π* 13 * (3π/4)/(2π) = 39π/4 ft
