Mathematics

Alika [10]3 years ago
5 0

<u>Given</u>:

Given that the diameter of the circle is 10 kilometers.

We need to determine the area of the circle.

<u>Radius of the circle:</u>

The radius of the circle can be determined using the formula,

r=\frac{d}{2}

Substituting d = 10, we get;

r=\frac{10}{2}

r=5

Thus, the radius of the circle is 5 kilometers.

<u>Area of the circle:</u>

The area of the circle can be determined using the formula,

A=\pi r^2

Substituting r = 5, we get;

A=(3.14)(5)^2

A=(3.14)(25)

A=78.5

Thus, the area of the circle is 78.5 square kilometers.

Answer:

The small balloon bouquet uses  7 balloons and the large one uses

18 balloons.

Step-by-step explanation:

Let's say that small balloon bouquets are S and large balloon bouquets are L. For the graduation party the employee assembled 6 small bouquets and 6 large bouquets, the total number of balloon used is 150. To put the sentence into an equation will be:

6S + 6L= 150

S+L= 25   ----> 1st equation

For Father's Day, the employee uses 6 small bouquet and 1 large bouquet, the total number of balloons used is 60. The equation will be:

6S + 1L= 60

1L= 60- 6S   ----> 2nd equation

We can solve the number of small balloon bouquet by substitute the 2nd equation into 1st. The calculation will be:

S+L = 25

S+ (60-6S)= 25

-5S= 25-60

-5S= -35

S= -35/-5

S=7

Then we can find L by substitute S value to 1st or 2nd equation.

S+L=25

7+L=25

L=18

Hope this helps ;)
