Answer:
v = 2034.72 mm³
Step-by-step explanation:
radius = 18mm
height = 6mm
pi = 3.14
v = πr²h/3
v = 3.14 * (18mm)² x 6mm/3
v = 3.14 * 324mm² x 2mm
v = 2034.72 mm³
Answer:
A) 2 1/12
Step-by-step explanation:
I just added all the fractions and subtracted from 10 1/12 :)
X= dad's age
y= 1/3x= boy's age
x+y=52
Substitute y=1/3x
x+1/3x=52
1 1/3x= 52
4/3x= 52
Multiply by reciprocal on both sides
(3/4)(4/3x)= (52)3/4)
x= (52*3)/4
x= 156/4
x=39 dad's age
Substitute x answer in to find boy's
y= 1/3x= 1/3(39)= (1*39)/3= 39/3= 13 boy's age
Check:
13+39= 52
Hope this helps! :)
