What is the equation of a circle with a radius of 7 and centered at point (3,-4)​
Hitman42 [59]

Answer:

(x - 3)² + (y + 4)² = 49

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + *y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (3, - 4) and r = 7 , then

(x - 3)² + (y - (- 4) )² = 7² , that is

(x - 3)² + (y + 4)² = 49 ← equation of circle

The perimeter of a rectangle is 68 inches. The perimeter equals twice the length of L inches, plus twice the width of 9 inches.
jok3333 [9.3K]
P=68

P=2L+2(9)

-----------------

Therefore:

2L+2(9)=68

2L+18=68

2L=68-18

2L=50

L=50/2

L=25

---------------

So the length is equal to <u>25 inches</u>.

What is 1/4 x 4p?! FAST PLEASE
Varvara68 [4.7K]
1/4 x 4p
Four (4) is equal to (=) 4/1, because 4 divided by 1 is still just 4.
=1/4 x 4/1p
The 1/4 and the 4/1 cancel each other out because we multiply the numerators and denominators to just get 4/4 which can be simplified to the number 1.
=1 x p
= p
