Your question has been heard loud and clear.
Alright , so basically , the area of a circle formula = pi * R squared
R = radius = 4 units
Pi = 3.14
So , Area = 3.14 into 4 = 12.56 units
So Area of the circle = 12.56 units
Thank you
6. When one number is a multiple of the other number, that would make the first number the LCM. For example if your first number is 14 and the second number is 2, their first common multiple would be when 2 gets to 14.
2, 4, 6, 8, 10, 12, 14.
14 would be the first time the numbers are equal
5. The first thing to do to find out if 8 is a multiple of 56 is to divide 56 by 8 and see if it comes out to a whole number. 56/8=7
Since 7 is whole, 56 would be the LCM of 56 and 8.
8, 16, 24, 32, 42, 48, 56
Answer:
12 inches
Step-by-step explanation:
Raj tested his new flashlight by shinning it on his bedroom wall the beam of the light can be described by the equation (x^2-2x) + (y^2-4y) - 31=0. how many inches wide is the beam of light on the wall
Solution
Given:
(x^2-2x) + (y^2-4y) - 31=0
By completing the square
(x^2-2x) + (y^2-4y) - 31=0
(x^2-2x+1-1) + (y^2-4y+4-4)-31=0
(x-1)^2 -1 + (y-2)^2 - 4 - 31=0
(x-1)^2 + (y-2)^2 - 1 - 4 - 31=0
(x-1)^2 + (y-2)^2 - 36=0
(x-1)^2 + (y-2)^2=36
Writing the equation in the form: (x-h)^2+(y-k)^2=r^2
(x-1)^2+(y-2)^2=6^2
From the above, r=6
Where,
r=radius
how wide is the diameter ?
radius=6
Diameter= 2 × radius
=2×6
=12 inches
Height of cylinder = h = 7.006 feet
Step-by-step explanation:
<u>We are given:</u>
Volume of cylinder = 1408 cubic feet
Radius = 8 feet
<u>We need to find:</u>
Height of cylinder = ?
<u>Formula used:</u>
Putting values in the formula and finding height:
So, Height of cylinder = h = 7.006 feet

I wanna say A. y = 3x + 5 y= 1/2x + 2 but I really am not sure
Hope that I kinda helped
