Answer:
The diameter of the base of the cylinder is 2 cm.
Step-by-step explanation:
<u>GIVEN</u> :
As per given question we have provided that :
- ➣ Height of cylinder = 14 cm
- ➣ Curved surface area = 88 cm²
<u>TO</u><u> </u><u>FIND</u> :
in the provided question we need to find :
- ➠ Radius of cylinder
- ➠ Diameter of cylinder
<u>USING</u><u> </u><u>FORMULAS</u> :
- ➛ Csa = Curved surface area
- ➛ π = 22/7
- ➛ r = radius
- ➛ h = height
- ➛ d = diameter
<u>SOLUTION</u> :
Firstly, finding the radius of cylinder by substituting the values in the formula :
Hence, the radius of cylinder is 1 cm.
———————————————————————
Now, finding the diameter of cylinder by substituting the values in the formula :
Hence, the diameter of the base of the cylinder is 2 cm.
True because b will always be +1 than a
Answer:
-14/15
Step-by-step explanation:
turn the denominator of -6/5 to 15 by multiplying 3 to the denominator and the numerator changing the decimal to -18/15+4/15= -14/15
Answer:
Rate of Bill's boat = 14 miles per hour
Speed of the current = 2 miles per hour
Step-by-step explanation:
Let x = the rate of the boat in still water and y = the rate of the current.
Distance traveled = 24 miles
Time taken for upstream motion = 2 hour
Time taken for downstream motion = 1.5 hour
Velocity of upstream motion = x - y
Velocity of downstream motion = x + y
We have
Displacement = Time x Velocity
Upstream motion
24 = 2(x-y)
x - y = 12 ----------------------------eqn 1
Downstream motion
24 = 1.5(x+y)
x + y = 16 ----------------------------eqn 2
eqn 1 + eqn 2
2 x = 28
x = 14 miles per hour
Substituting in eqn 2
14 + y = 16
y = 2 miles per hour
Rate of Bill's boat = 14 miles per hour
Speed of the current = 2 miles per hour
