The answer is D 105 because i know
Answer 4
4multiplyed by 4 is 16
Answer:
C ≈ 14.18
Step-by-step explanation:
<u><em>Question Given:</em></u>
A circle has an area of 16mm². Find it's circumference.
<u><em>Formula:</em></u>
C = 2√πA
<u><em>Solve:</em></u>
C = 2√πA
C = 2√(3.14 × 16)
C = 2√50.24
C = 14.1760361173
C ≈ 14.18
<em>Hence, Circumference is approximately 14.18.</em>

3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2
2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3
perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3.
So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==
