Answer:
arc AB = 70°
arc BC = 110°
arc ABC = 180°
arc CDB = 250°
Step-by-step explanation:
Since these angles are not inscribed, but are at the center point of the circle, the angles and arcs will be the same measure.
Solve for arc AB:
Angle AFB = 70°, so arc AB = 70°
Solve for arc BC:
Angle AFC is a straight angle so it is 180°. To find angle BFC, subtract angle AFB from 180°.
180 - 70 = 110°
Since angle BFC = 110°, arc BC = 110°
Solve for arc ABC:
Add arc AB and arc BC together.
70° + 110° = 180°
arc ABC = 180°
Solve for arc CDB:
There are 360° in a cirlce. To find arc CDB, subtract arc BC from 360°.
360° - 110° = 250°
arc CDB = 250°
Well, if Sameer's plum was 32 calories, and we know his total snack was 56 calories, all we have to do is:
56-32=24
24 / 4 = 6
Sameer ate one plum (32Kcal) and 6 strawberries (4Kcal each)
The total cost of the camera is $268.26
A down payment of $12 was paid so he now owes $256.26
Every 6 months Emil has to pay:
256.26 / 6 = 42.71
Therefore, each moth, Emil has to pay $42.71
Answer:
30
120
706.5
Step-by-step explanation:
circumference= 94.2 inches, circumference is pi x diameter so-
diameter = 94.2/pi inches.
Using 3.14 as an approximation for pi we get:
Diameter=30 inches.
So would need a length of at least
4x30 = 120 inches of felt for four wheels.
The area of the circular wheel is pi x diameter 2/4 square inches.
Area is 706.5 square inches which is how much felt is needed to cover one wheel.
Answer:
true
