Its C because the 18in is the height, the 12in is the width, the 24in is the length. Which you just multiply together.
Answer:
S = 9.9
Step-by-step explanation:
First, multiply by -3 to remove fractions:
so:
S - 38.4 = -28.5
Take all values to one side by adding 38.4 to both sides
S = 9.9
1/3 = 0.333333
87/100 = 0.87
The formula for length of an arc on a circle is given by the formula:
,
where 'r' is the radius of the circle and 'x' is the measure of the central angle of the arc.
We have to determine the value of radius 'r'.
Since, 
By Cross multiplication, we get




Therefore, the radius 'r' is given by
.
Option 4 is the correct answer.
