The last answer would be correct because a closed cicle on a number line is less than/greater than or equal to and an open circle is less than or greater than. Because you are going to the left, into negatives, your answer would be d.
The radius of the table top, rounded to 1 dp is 5.6 cm
From the question,
We are to determine the radius of the table top
First, we will determine the volume of the cylindrical wooden table
From the given information
Density = 0.42 g/cm³
Mass = 0.25 kg = 250 g
Using the formula
∴
Volume = 595.238 cm³
Now, for the radius of the table top
Using the formula for volume of a cylinder
Where V is the volume
r is the radius
and h is the height or depth
From the given information
h = 6cm
Putting the parameters into the formula
∴
r = 5.6 cm
Hence, the radius of the table top, rounded to 1 dp is 5.6 cm
