Answer:
3053.5517 cm^3 ; 1/8
Step-by-step explanation:
Given the following :
Volume (V) of sphere = (4/3)πr^3 where r = radius
Diameter of sphere = 18 ; radius(r) = diameter / 2 = 18/2 = 9cm
V = (4/3) × π × 9^3
V = 1.3333 × π × 729
V = 3053.5517 cm^3
When diameter(d) is reduced to half
d = d/2
Volume (V1) of sphere with diameter 'd' =
V1 = (4/3)π(d/2)^3
Volume (V2) of sphere with diameter 'd' reduced to half, d = d/2, d/2 * 1/2 = d/4
V2 = (4/3)π(d/4)^3
V1 / V2 = [(4/3)π(d/2)^3] / [(4/3)π(d/4)^3]
V1 / V2 = (d/2)^3 / (d/4)^3
V1 / V2 = [d^3 / 2^3] / [d^3 / 4^3]
V1 / V2 = 8 / 64
V1 / V2 = 1 / 8
Answer:
hi
Step-by-step explanation:
The gradient(slope) is 3.
The y-intercept is 0.
Using the slope-intercept form,
y=3x%2B0
y=3x
Answer:
Step-by-step explanation:
Let 
be the number of gallons so 
is the number of miles traveled per gallons.
We know for our problem that Brian's car gets 25 miles per gallon. Since the gallons is represented by , his car will travel a total distance of 25g (where g is the number of gallons.
We also know that the total distance is given by , so we can put the two expressions together to get our function:
Let's check:
- If he uses 1 gallon (g=1), so
miles
He will travel 25 miles with one gallon.
- If he uses 2 gallons (g=2), so
He will travel 50 miles with two gallon.
Answer:
I’d say C
Step-by-step explanation:
You should divide 112340 by 125. Then multiply it by 157. The result will be the closest to C.
25 units first u go along the x axis then the y then you get ur answer
