Diameter=16mm, so the radius is 8. The formula for volume of a cylinder is the area of the base times height, or v=πr²h.
Substituting the values in, we get π(8²)(5.7), which gives us roughly 1146mm^3.
The answer is 169 ..... I hope this helps :)
X + 4x = 40
5x = 40
5x/5 = 40/5
x = 8
1x 8 = 8
4x 8 = 32
Check=
8 + 32 = 40
The numbers are 8 and 32
Answer:
24
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=24
Answer:
35 quizzes
Step-by-step explanation:
We need to determine how many ways we can choose 4 questions out of 7 to make the quizzes.
We do this by using the formula 
which describes the number of ways we can choose 
objects given 
possible choices. So, if 
and 
, then:
Hence, the teacher can make 35 different geometry quizzes.
