What is the circumference of a circle with an area of 16π in²

Mathematics

Answer: 8pi

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

Explanation:

A = 16pi is the area, which means
A = pi*r^2
16pi = pi*r^2
16 = r^2
r^2 = 16
r = sqrt(16)
r = 4 
is the radius

Use this to find the circumference C
C = 2*pi*r
C = 2*pi*4
C = 8pi
The exact circumference is 8pi inches long

The perimeter of a rectangular field is 302 yards. If the width of the field is 65 yards, what is its length?​
Molodets [167]

Answer:

L= 86 yards

Step-by-step explanation:

Perimeter = 2length + 2width

So,

302= 65(2) + 2(L)

302= 130+2L

-130

172=2L

Length= 86

Step-by-step explanation:

The algebraic representation that correctly describes a reflection over the x-axis is (x, y) → (x, -y)

Here's an example to show understanding

Plot A is (4,6) and the reflection over the x-axis would be (4,-6)
