Answer:
1 hour and 17 minutes and 7 sec
Step-by-step explanation:
.
Roll 1: 1 number out of 6 total numbers = 1/6
Roll 2: 1 number out of 6 total numbers = 1/6
Roll 3: 1 number out of 6 total numbers = 1/6
Roll 4: 1 number out of 6 total numbers = 1/6
Roll 1 AND Roll 2 AND Roll 3 AND Roll 4
1/6 x 1/6 x 1/6 x 1/6 = 1/1296
Answer:
Option B is correct.
Step-by-step explanation:
The distance formula used is:

We need to find distance between origin and other point (3,-4,5)
Origin is: (0,0,0)
x₁ = 0, y₁ = 0, z₁ =0 and x₂= 3, y₂= -4 and z₂ = 5
Putting values in the distance formula we get:

The Distance from the origin to the point (3, −4, 5) is 7 units.
Option B is correct.
Answer: 48.8
Step-by-step explanation: The equation for the area of a circle is π*r², since the base of a cylinder is a circle we take the equation of a circle and multiply the height of the cynlinder by using the equation π*r²*h to get the volume of a cylinder. In this case our factors are
π= 3.14
r²= 6.76
h=2.3
3.14*6.76*2.3=48.82072
rounded to the nearest tenth=48.8
Hello!
To find the volume of a cone you do

r is radius
h is height
Put in the values we know and 3.14 for pi

Multiply and you get 619.10
The answer is 619.10 cubic cm
