Answer:
The answer is 64 cm3.
Step-by-step explanation:
We would use the formula V=4/3 pi r subscript3.
Substitude the numbers in.
V=4/3 pi 48
so, 4 times 48= 192
192 divide by 3=64
So the answer is 64.!
Answer:
A. 1,500m
B. 2000m
C. 1875m
Step-by-step explanation:
A. Here, we simply substitute the value of t in the equation.
t = 5min
V(t) = 400 - 20t
= 400 - 20(5)
= 400 - 100 = 300m/min
Now we know that distance = speed * time = 300 * 5 = 1,500m
2. Substitute t = 10
V = 400 - 20(10) = 400 - 200 = 200m/min
Distance = speed * time = 200 * 10 = 2000m
3. Here we need to calculate time
Rearranging the equation:
20t = 400 - V(t)
20t = 400 - 250
20t = 150
t = 150/20 = 7.5min
Distance traveled = 250 * 7.5 =1875m
