A. The circumference of a circle is the diameter times 3.14 aka pie and for instance, if you have two circles, circle A has a radius of 2 and diameter of 4 and circle B has a radius of 4 and diameter of 8, then if you compare the radius to the diameter (2/4 and 4/8) you get 1/2 for both and you know the circles are similar
Answer: About 21 inches
Step-by-step explanation:
62.4 divided by 3 is 20.8
20.8 is rounded to 21 to estimate
Let's go ahead and find the volume of a prism, then double the dimensions and see what happens to the volume. Then we can apply it to your volume.
volume of a prism with dimensions 2x2x2
v= 2x2x2 = 8 units^3
Now let's double it
volume of prism with dimensions 4x4x4
v= 4x4x4 = 64 units^3
So we see that by doubling the dimensions we multiply the volume by a factor of 8. Let's do that for your volume, 3.5 m^3
3.5 x 8 = 28 m^3
Answer:
- y = -3/5 × -5 - 2
- y = 2 × -1 + 2
Step-by-step explanation:
#1
- y = mx + b
- m = -3/5, x = -5, b = -2, y = y
- put in correct order
#2
- (2, -1) - (5,5) = 6/3 = 2/1 = 2 (remember, y is over x. The formula is y2 - y1 / x2 - x1)
- Pick either point given (2, -1) or (5, 5)
- Plug the point in
- y = y, m = 2, x = 2, b = -1
- Put in order
