Answer:
d = 28
r = 14
r² = 196
C = 87.92
Step-by-step explanation:
Given:
r = 14
To find diameter:
d = 2r
d = 2(14)
d = 28
To find r²:
14²
196
Circumference:
C = 2πr
C = 2(3.14)(14)
C = 87.92
The selling price would be 55
50x10%=5
50+5=55
Area is the area of something and the premeter of something
Answer:
300 students
Step-by-step explanation:
There are two ways to solve this question.
60 is 20% of the total students
20÷100= 0.2
60÷0.2=300
Therefore there are 300 students
60 is 20% of the total students
60/20 = x/100
x= 60*100÷20
x= 6000÷20
x= 300
Therefore there are 300 students.
