60 + 90
GCF = 30
(30 * 2) + (30 * 3) = 30(2 + 3) <== the correct way
The mistake Axial made was he did not pick the greatest common factor...he picked 3 instead of 30.
Answer:
Figure B
Step-by-step explanation:
Circumference of a circle is simply the length of the boundary of the circle which can be measured by the formula of
In the figure B the given radius in the figure is 5
Putting 5 in the formula to find the circumference of the circle gives
= :
Circumference of the circle in fig B = 31.4 cm
So, Circle in the figure B will have the circumference of 31.4 cm. Also the Circumference of the fig A, C and D are different and are not equal to 31.4 cm

Answer:
29 kg
Step-by-step explanation:
1 lb = 0.45359237 kg
65 lb * (0.45359237 kg)/lb = 29 kg
volume for the glass 2= 3.14*2.5^2*6/3 = 39.25 cubic cm
60-39.25 = 20.75
glass 1 holds 20.75 cubic cm
height is 20.75 = 3.14*2^2*h
20.75 = 12.56*h
h = 20.75 / 12.56 = 1.65 round to 1.7 centimeters
