Answer:
616 cm²
Step-by-step explanation:
To find the area of a circle you use the formula A = π · r²
So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.
196 × (22/7) = 616

Answer:
Median = 31
Step-by-step explanation:
The median is the middle number which comes after arranging the set in ascending order.
Here, the given data is: 28, 45, 12, 34, 36, 45, 19, 20
The data arranged in the ascending order is as follows:
12, 19, 20, 28, 34, 36, 45, 45
Since the number of terms is even, we have two middle numbers, viz.,
28 and 34
The median would be the average of these two.
Therefore, Median = 28+34/2
= 31
The answer is 31.
