p=4w+12
Answer:
1) 6*5-4
2) 17 - (5+9)
Step-by-step explanation:
Step-by-step explanation:
Volume of a cylinder : πr^2*height.
Volume : 150cm^3
height : 7.2m
π =3.14
150 = 3.14*r*r*7.2
150=22.608*r*r
r^2= 150/22.608
=150/23cm^2
r=√6.5
r=2.569cm
r=2.6cm
19 x 1 = 19 and 1 x 19 = 19
These ratios are equivalent because 7 and 8 can be multiplied by 6 to get 42 and 48.
