4 prints
12x = 2.5x + 38
at 4, these expressions are equal
Answer:
3.8%
Step-by-step explanation:
90/2358=0.038
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
Answer:
Alright well just move all terms that don't contain x to the right side and solve
Exact form: 5/3
Decimal form: 1.6 Hope this helps :)
Step-by-step explanation:
Answer:
The radius of the circle is 9 units.
Step-by-step explanation:
To calculate the area of the circle we need to find it's radius, since we have the area of the sector and it's angle, therefore we can calculate the radius by using the following formula:
sector area = (central angle)*pi*r²/360
27pi = 120*pi*r²/360
27pi = pi*r²/3
27 = r²/3
r² = 81
r = sqrt(81) = 9
The radius of the circle is 9 units.
