Answer 2

From the information given, the area of the circle is: "113 sq. cm".

What is mean by Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

The formula to find the area of a circle is,

Area = πr².

Now, Using the side as the radius of the circle, we can calculate the area of the base area.

Here,

Radius r = 6

Thus, We get;

A = π x 6²

A = (22/7) x 36

A = 3.14285714286 x 36

A = 113.12

A ≈ 113 square unit.

Hence, The area of the circle is,

⇒ A =  113 sq. cm.

find the value of x.

Answers

Answer:

x = 14.5

Step-by-step explanation:

This is a supplementary angle, meaning the sum of the angles is 180°.

We can find the value of x by combining like terms.

5x - 6 + 7x + 12 = 180.

5x and 7x are alike.

5x + 7x = 12x.

-6 + 12 = 6.

The final equation is 12x + 6 = 180.

We can solve this by subtracting 6 from 180.

180 - 6 = 174.

12x = 174

Lastly, we divide 174 by 12.

174 / 12 = 14.5

Therefore, x is equal to 14.5

58°

Step-by-step explanation:

A flat angle equals 180°, so we can simply subtract the given angle from the total, 180.

180 - 122 = 58

So, ∠CDE = 58°.

Good luck n.n

Answer:

58°

Step-by-step explanation:

∠AEC =∠AED+∠CED

So,

∠AEC=180°

∠AED=122°

∠CED=?

∠AEC =∠AED+∠CED

180°=122°+∠CED

∠CED=180°-122°

∠CED=58°

Answers

The answer is To your question is C

The steps to take to make sure he bought enough fence are

Covert both sides to the same units.Compare the number of feet of fence he bought with the number of feet of fence he needs

The perimeter of the rectangular fence is 42 feets.

Properties of a rectangle.Opposite sides are equal.Opposite sides are parallel.The angles are right angle.

Therefore, two sides of the garden are 12 feet each long. The other two sides are 108 inches long.

The steps to take to make sure he bought enough fence is as follows:

Covert both sides to the same units.Compare the number of feet of fence he bought with the number of feet of fence he needs.

Therefore,

108 inches = 9 ft

Therefore,

12 + 12 + 9 + 9 = 42 feet's.

He bought 40 feet fence. Therefore, he needs 42 feet's of fence which means the fencing will not be enough.

The function y=60+25sin(pi/6)t, where t is in months and t=0 corresponds to April 15, models the average high temperature in degrees Fahrenheit in Centerville.

b.) What is the maximum high temperature and when does this occur?

NOTE: I found the answer online, I just don't understand how to get there. It's July 15, 85 degrees.

Answers

Answer:

The maximum temperature will be of 85 degrees, on July 15.

Step-by-step explanation:

Sine function:

The sine function oscilates between -1 and 1, and it's maximum value is:

[tex]\sin{(\frac{\pi}{2})} = 1[/tex]

y=60+25sin(pi/6)t

The maximum value will occur when [tex]\sin{(\frac{\pi t}{6}}) = 1[/tex], and it will be of 60 + 25 = 85 degrees.

When will it occur?

First we find the value of t for which the value inside the function sine is [tex]\frac{\pi}{2}[/tex]. So

[tex]\frac{\pi t}{6} = \frac{\pi}{2}[/tex]

[tex]\frac{t}{6} = \frac{1}{2}[/tex]

[tex]2t = 6[/tex]

[tex]t = \frac{6}{2} = 3[/tex]

That is the number of months after April 15, which is 3 months. So July 15.
