4 is not a factor because it does not multiply with anything to make forty except 10.5 but it can't be a decimal
Answer:
3,6 or 4,6?
Step-by-step explanation:
We know that
360°/12 hour-----------> 30°/hour
<span>Central angle at 4 .00 is 120 degrees
the radius of a clock is 6/2-----> r=3 in
length of a circumference=2*pi*r-----> 2*pi*3----> 18.84 in
the minor arc at 4 .00 is for a central angle of 120</span>°
so
if 360° (full circle)---------> has a length of 18.84 in
120°----------------------> X
X=120*18.84/360-------> X=6.28 in
the answer is
6.28 in
Perimeter = 4 x sides
48 = 4 (x + 3)
48 = 4x + 12
36 = 4x
x = 9
Check:
x + 3 = 9 + 3 = 12
12 x 4 = 48
