Your answer is B. 0.9272. Hope I was able to help!
Step-by-step explanation:
the volume of a cylinder is
base area × height = pi×r² × height
with r being the radius.
so, we get
pi×6² × 10 = pi×36 + 10 = 360pi =
= 1,130.973355... ft³
now we need to look at the conversion rate between feet and meters :
1 ft = 0.3048 m
1 ft² = 0.3048² m² = 0.09290304 m²
1 f³ = 0.3048³ m³ = 0.028316847... m³
1,130.973355... ft³ = 1,130.973355... × 0.028316847... =
= 32.025599... m³
so, something is not right with your answer options. it looks like you put maybe the answer options of a different question in here.
but none of them get even close to the actual solution of the given question.
Volume of a Rectangular Prism: V=lwh
l=50 cm
w= 30cm
h= 40 cm
Step 1: 50×30×40= 60,000
The volume of the tank is 60,000 cubic centimeters
The water reaches a height of 28 centimeters, or 2142.9 cubic centimeters per centimeter.
Step 2: 35× 2142.9= 75001.5 cubic centimeters
Step 3) 75001.5- 60,000= 15001.5 CUBIC CENTIMETERS ARE NEEDED TO FILL THE REST OF THE TANK TO A HEIGHT OF 35 CENTIMETERS
Hope this helps!
Subtract the rental fee, then divide the left over amount by the cost per hour.
38-10 = 28
28 / 7 = 4
The answer is 4 hours.
