Find the circumference and the area of a circle with radius 6 km. Write your answers in terms of it, and be sure to include the correct units in your answers.

Circumference: 12pi or 37.7

Area: 36pi or 113.1

Step-by-step explanation:

C = 2(pi)r

C = 2 * pi * 6

C = 12pi or 37.7

A = (pi)r^2

A = pi * 6^2

A = 36pi or 113.1

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
