Answer:
Step-by-step explanation:
Area of sector = (∅/360°) x πr²
Area of sector = 48cm²
radius = 4cm
π = 3.14
48 = (∅/360°) x 3.14 x 4 x4
48 = (∅/360°) x 50.24
48/50.24 =(∅/360°)
0.9554 = (∅/360°)
∅ = 0.9554 x 360 = 343.949≈343.95° ( these is when the angle is in degrees)
if it is radians
area of sector = 1/2r²∅
area of sector = 48
r = radius = 4
area of sector = 1/2r²∅
48 = 1/2 x 4 x4 x∅
48 = 2x4 x∅
48 = 8∅
∅ = 48/8 = 6 radians
the central angle in radians is 6
Answer:
y=34
x=10
Step-by-step explanation:
Step-by-step explanation:
We know that
Volume of square pyramid = a² × h/3
=> (12)² × 8/3
=> 144 × 8/3
=> 48 × 8
=> 384 in³
Now,
We need to find ratio for finding the times of the volume
=> 3456/384
=> 9
Hence,
Volume of pyramid B is 9 times greater than the volume of pyramid A
Answer:
m=18
Step-by-step explanation:
First add 7 to both sides.
2+7=m/2
Simplify 2+7 to 9
9=m/2
Multiply both sides by 2
9*2=m
Simplify 9*2 = 18
18=m
47 - 11.50 = $35.50 needs to be earned.
If she works 6 hours:
6.50 x 4 = 26
5.25 x 2 = 10.50
26 + 10.50 = $36.50 how much she would earn by working 6 hours.
when you add the amount of money she would earn for working 6 hours $36.50 plus the money she had already had saved up $11.50 the total amount of money she would have is $48.00
So, yes. She would be able to go on the field trip if she worked at both jobs to 6 hours.
