Step-by-step explanation:

step 1. the area of a circle is A. A = (pi)r^2.

step 2. if the diameter is 8 cm then the radius is 4 cm.

step 3. A = (pi)4^2

step 4. A = 16(pi) = 50.24 cm.

Answer:

Step-by-step explanation:

A=\pir^{2}                            Diamter is half the radius so the radius is 4

A= 3.14 times 4^{2}                       4^{2}= 16

A= 3.14 times 16

A=50.24

rounded answer will be 50.2

snow_tiger [21]

The average score of all the students in both classes is 84.

<h3>How to calculate the average?</h3>

The class with 30 students had an average score of 80 on a test. The total score will be:

= 30 × 80

= 2400

A class with 20 students had an average score of 90 on the same test. The total score will be:

= 20 × 90

= 1800

Total scores = 2400 + 1800 = 4200

Number of students = 20 + 30 = 50

The average score will be:

= Total score / Total students

= 4200 / 50

= 84
