Find the area of a circle with diameter 12 cm.

luda_lava [24]

Answer:

113.04 cm.

Step-by-step explanation:

Step 1: Formula/explain

To find the area of a circle, multiply the radius by itself twice, then multiply the product pi.

$a=\pi r^2(3.14*radius*radius)$

Step 2: Solve

According to the word problem, the circle has a diameter of 12. This means it has a radius of 6.

Now, we plug the numbers into formula.

$\pi 6^2 (3.14*6*6)=113.04$

Step 3: Conclude

Therefore, the area of this circle is 113.04 cm.

School rules permit no fewer than 2 teachers per 25 students. There are at least 245 students enrolled in the school. If x repre

NISA [10]

First, let's write down this inequality:
There are at least 245 students enrolled in the school.

y≥245

This inequality says what the sentence says!

now, the number of teachers must be:
x≥2*(y/25)
(two times the number of groups of students of 25!)

so those two inequalities, taken together will be the answer!
