Answer:
1.) Circumference of circle A = 131.95 metre
2.) Circumference of circle B = 175.93 metre
3.) Yes. Radius is proportional to the circumference.
Step-by-step explanation: Given that Circle A has a radius of 21 meters and Circle B has a radius of 28 meters
Circumference of a circle = 2πr
For circle A
Radius r = 21
Circumference = 2 × 3.143 × 21
Circumference = 131.95 metre
For circle B
Circumference = 2 × 3.143 × 28
Circumference = 175.93 metre
Is the relationship between the radius of a circle and the distance around the circle the same for all circles? YES
Because the radius of the circle is proportional to the distance around them ( circumference ) for all the circle. That is, the larger the radius, the larger the circumference
No this is not a right triangle in order for it to be a right triangle 30 sides for instance line AB would have to equal 90 degrees
Simple Interest , I = PRT/100
Where P = Principal, R = Rate, T = Time in years
Time, T = (100*I)/(P*R)
T = 100* 84 / (600 * 7) Use your calculator
T = 2
Time is 2 years.
Answer:21 male drink only coffee
The probability of the probability that any person is male is 0,21
but if you need the probability of the males is 0,57
Step-by-step explanation:
number of people:100
number of males:57
number of males whos drink only coffee:21
number of males whos drink only coffee / number of people= 
9.647 x 10^7 should be the unrounded answer
