A class of 30 students took midterm science exams. 20 students passed the chemistry exam, 14 students passed physics, and 6 stud

sergejj [24]

Answer:

Step-by-step explanation:

Given :

Total students = 30

Students passed chemistry exam = 20

Students passed physics exam = 14

Students passed both exams = 6

To find: Venn diagram

Solution:

Total students = 30 i.e. U = 30

Students passed chemistry exam = 20

Students passed physics exam = 14

Students passed both exams = 6

Students passed only chemistry = 20-6 =14

Students passed only Physics = 14-6=6

So refer the attached figure for the Venn diagram

Find the circumference. use 3.14 for π r=2 cm c=? c=π d<br> help please

Helga [31]

Answer:

C = 12.56m

Step-by-step explanation:

circumference is the distance around the outside of a circle. The r stands for radius, half way across, from the center(thats the little line on the diagram) "d" stands for diameter. That would be double the radius, bc its all the way across the circle through the center. The formula to find the CIRCUMFERENCE is given, C=pi × d

They told you to use 3.14 for pi. And also the radius is 2, so the diameter is 4

C = pi × d

C = 3.14 × 4

C = 12.56 meters
