What is the area of the circle?

Mathematics
1 answer:
dmitriy555 [2]3 years ago
8 0

We know that the area of a circle has the formula A=πr²

We are given the diameter, and as we know that the diameter is twice the radius, we can divide the given diameter by 2.

27 ÷ 2= 13.5

Now, plug-in the number into the formula.

A=πr²

A=π×13.5²

A=π×182.25

(Assume π=3.14)

A=3.14 × 182.25

A=572.265

A=572.3 square meters.

Therefore, the area of the circle is 572.3 square meters.

F(m) = 2.5 + 0.12m

if Natalie paid $6.82

6.82 = 2.5 + 0.12m
0.12m = 6.82 - 2.5
0.12m = 4.32

A university's freshman class has 6200 students. 4836 of those students are majoring
WINSTONCH [101]

According to the solving 78% of the freshman class are Economics majors.

<h3>What does a percentage mean?</h3>

percentage, a relative figure signifying hundredths of any amount. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

<h3>Why is it called percent?</h3>

The word "percent" comes from the Latin adverb per centum, which means "by the hundred." In the sixteenth century, the Latin expression made its way into English. Later, it was shortened to % with a final period.

<h3>According to the given data:</h3>

It is given that the total number of students in freshman class = 6200

Total number of students majoring in Economics = 4836

Here, we are asked to find the percentage of the freshman class who are majoring in Economics.

Percent of students majoring Economics =  (Number of students majoring/ Economics  Total number of students) x 100

= \frac{4836}{6200} x 100

= 78%

According to the solving 78% of the freshman class are Economics majors.
