Answer:
$640 is how much she will make in in regular hours.
Step-by-step explanation:
Create an equation from the word problem and solve.
1.
v of cylinder=πr^2*h
3.14*8^2*18
BEDMAS
3.14*64*18
201*18
3168
there fore the volume is 3168
do the same thing but with the formula of cone volume for question 2
G.......................................
a) 5 m
b) 8 yd
Step-by-step explanation:
a) Take the ratios of the legs of the triangles. Since they are similar triangles, those ratios are equal.
d/(4 m) = (10m)/(8 m)
Solving for d,
d =(10/8)(4 m) = 5 m
b) m/(10 yd) = (12 yd)/(10 yd + 5 yd) = 12/15 = 4/5
Solving for m,
m = (4/5)(10 yd)
= 8 yd
Answer:
39 feet.
Step-by-step explanation:
E use the Pythagoras theorem:
40^2 = 8^2 + h^2 as h is the height we require.
h^2 = 1600 - 64
h^2 = 1536
h = 39.19 feet
