0.5 => 5/10 => 1/2
12.3 => 123/10
0.07 => 7/100
0.625 => 625/1000 => 25/40 => 5/8
Answer:
Factors of 8 are 2,4 and 8.
Step-by-step explanation:
Your answer was correct . Maybe you have an extra space in your answer ? I worked out the problem twice and got -49/8, -163/8
The answer is true because -42+10 is -52
Answer:
138π m²
Step-by-step explanation:
The following data were obtained from the question:
Diameter (d) = 6 m
Height (h) = 20 m
Surface Area (SA) =?
Next, we shall determine the radius. This can be obtained as follow:
Diameter (d) = 6 m
Radius (r) =?
r = d/2
r = 6/2
r = 3 m
Finally, we shall determine the surface area of the cylinder. This can be obtained as follow:
Radius (r) = 3 m
Height (h) = 20 m
Surface Area (SA) =?
SA = 2πrh + 2πr²
SA = 2πr (h + r)
SA = 2 × π × 3 (20 + 3)
SA = 2 × π × 3 × 23
SA = 138π m²
Thus, the surface area is 138π m².
