Find the equation of circle having centre with

Mathematics
1 answer:
GaryK [48]2 years ago
3 0

Step-by-step explanation:

Simply use the general equation of a circle to obtain its equation given the center. Because radius is 5 units, this may be referred to the 3-4-5 triangle, meaning the point on circumference is 3 units across in the x-direction and 4 units up in the y-direction.

80 square units
Divide the figure into 4 small triangles, 2 rectangles, and one big rectangle on the center.

Area of ONE small triangle:
1/2 • 2 • 2 = 2 square units
Multiply that by 4 because we have 4 small triangles: 2 • 4 = 8 square units

Area of ONE small rectangle:
2 • 6 = 12 square units
Multiply that by 2 bcos we have 2 of those rectangles: 12 • 2 = 24 square units

Area of the big rectangle on the center:
6 • 8 = 48 square units

ADD the area of the big rectangle, 4 small triangles, and 2 small rectangles:
48 + 24 + 8 = 80

FINAL ANSWER: 80 square units

A vacant lot is being converted into a community garden. The garden and and a walkway around its perimeter have an area of 460 s
mariarad [96]

Answer:

The width of the walkway is 4 feet.

Step-by-step explanation:

The garden and a walkway around its perimeter have an area of 460 square feet.

The length of the garden = 15 feet

The width of the garden = 12 feet

Assuming that walkway is of uniform width, we can solve the following equation.

(12+2x)\times(15+2x)= 460

Expanding this we get;

4x^{2}+54x+180=460

=> 4x^{2}+54x-280=0

We will solve this using quadratic equation formula:

x=\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}

Here a = 4 , b = 54 , c = -280

We get the roots as x = 4 and x = -\frac{35}{2}

Neglecting the negative value, we will take x = 4 feet.

Hence, the width of the walkway is 4 feet.

two angles are consecutive exterior to one another. if the angles are in ratio 11:7. Then find the supplement of the larger angl
Gwar [14]

If the ratio of two consecutive exterior angles are 11:7, the supplement of the larger angle will be <u>70 degrees</u>.

The larger angle and the smaller angle are supplementary to each other since they are consecutive exterior to one another.

  • <em><u>Thus</u></em>:

If the larger angle is x, therefore:

Ratio of Larger angle to smaller angle = 11:7

  • <em>Therefore</em>:

11x + 7x = 180 degrees

  • Solve for x

18x = 180

  • Divide both sides by 18

x = 10

Larger angle = 11x = 11(10) = 110 degrees

Smaller angle = 7x = 7(10) = 70 degrees

The supplement of the larger angle, 110 degrees, is <u>70 degrees.</u>

In summary, if the ratio of two consecutive exterior angles are 11:7, the supplement of the larger angle will be <u>70 degrees</u>.
