Answer:
A square
Step-by-step explanation:
A parallel cross section will be the same shape of the base. Since it's a square base, all parallel cross sections will also be parallel. Think of it as a different floor of a pyramid shaped building.
Answer:
The volume of the cone is 12936 cubic mm.
Step-by-step explanation:
Given
Circumference of base = 132 mm
Height of the cone = 28 mm
Solution
Formula of circumference =
= 132 mm

Now volume of cone = 
on substituting the value of r and h we get ;

thus volume of cone is 12936 cubic mm.
Answer:
It is a diagnal line that goes through (0,0) and (1,1) and has a slope of 1
Step-by-step explanation:
First we need to find the probability of selecting the 1 blue marble out of the 20 marbles total, which is 1/20.
Next, we need to find the probability of tossing the fair coin so it lands tails up, which is 1/2.
To find the probability of both events happening, we need to multiply the probabilities of the two individual events:
1/20 * 1/2 = 1/40
So the answer is 1/40, or 2.5%
