find the area of the circle. round your answer to the nearest hundredth
area of circle= 2cm

Answers

Answer 1

Answer:

3.14 cm squared

Step-by-step explanation:

First divide 2 by 2 which equals 1

Then you do pi which equals 3.14 and multiply it by 1^(2) (1 squared)

But you don't do 1 x 2 you do 1 x 1

then you get 3.14

So basically..... divide 2 by 2 then do 3.14 x 1^(2)

What is a law of sine?

Law of sines is a formula relating the length of the sides of a triangle to the angles of the triangle.

In Triangle JKL

< K J L = 58 degrees

< J L K = 38 degrees.

and, J K = 2.3,  J L = k.

As, <KJL + <JKL + <LKJ = 180

58+ 23 + <LKJ = 180

<LKJ = 99 degree.

Using Law of sines

k/ sin K = j/ sin J

k/ sin 99 = 2.3/ sin 58

k- 2.05

Write an equation of the circle with center (-2,5) radius 9

Answers

Answer:

(x+2)²+(y-5)² = 81

Step-by-step explanation:

The formula for calculating equation of a line is expressed as

(x-a)²+(y-b)² = r²

(a,b) are the points

r is the radius

Given

Point = (-2,5)

Radius = 9

Substitute

(x-(-2)²+(y-5)² = 9²

(x+2)²+(y-5)² = 81

Hence the required equation is (x+2)²+(y-5)² = 81
