Question

Can someone help with #8

Answer 1

Answer:

Step-by-step explanation:

9)

$Circumference=43.96cm\\\pi \pi*d=43.96\\\\3.14*d=43.96\\\\d=\frac{43.96}{3.14}\\\\d=\frac{43.96*100}{3.14*100}=\frac{4396}{314}\\\\d=14cm$

10)

$3.14*d=94.2\\\\d=\frac{94.2}{3.14}\\\\d=\frac{94.2*100}{3.14*100}\\\\d=\frac{9420}{314}\\\\d=30mm$
