Answer:
60 Cubic centimeters
84 Cubic centimeters
Step-by-step explanation:
0.5*6*5*4 = 60
0.5*4.2*5*8 = 84
10 ∙ 2 ∙ 19 ∙ 5 = (10 ∙ 2) ∙ (19 ∙ 5) = 20 ∙ 95 = 1,900
Answer:
8 units
Step-by-step explanation:
Note that 120 degrees represents 1/3 of 360 degrees. The arc described here is thus 1/3 of the circumference of this circle.
Find this circumference and then multiply that result by 1/3:
The formula for the circumference of a circle with radius r is C = 2πr. Here,
(1/3)*(2)(π)(4 units) = 8.38 units, or (to the nearest integer) approx. 8 units.
C. Normally when you are talking about money and how much he makes an hour plus allowance they want you to draw a graph so C is your answer.
volume = PI x r^2 x h
using 3.14 for pi
volume = 3.14 x 2^2 x 3
volume = 37.7 cubic cm of wax needed
Round answer as needed
