Answer:
8. C=131.88 mm
9. C=40.82 ft
10. A=254.34 in²
Step-by-step explanation:
8. diameter of 42 millimeters- circumference?
Radius is half of 42, so 21 mm
Circumference=2πr
C=2π21
C=131.88 mm
9. diameter of 13 ft- circumference?
radius is half of 13, so 6.5
Circumference=2πr
C=2π6.5
C=40.82 ft
10. radius of 9 in- area?
Area=πr²
A=π9²
A=π81
A=254.34 in²

Answer:
95
Step-by-step explanation:
35+50= 85
180-85=95
Answer:
82*
Step-by-step explanation:
10x+8 = 12x-10
18 = 2x
X=9
Angle 1 = 98*
Angle 3 = 98*
180 - 98* = 82*
To get the Greates Common Factor (GCF) of 72 and 200 we need to
factor each value first and then we choose all the copies of factors and
multiply them:
<span><span>72: 22233 </span><span>200: 222 55</span><span>GCF: 222 </span></span>
The Greatest Common Factor (GCF) is: 2 x 2 x 2 = 8
Answer: 8
