Step-by-step explanation:
We know that we have the formula that F = ma
Given
Force (F) = 7.5 N
Acceleration (a) = 15 m/s²
Mass (m) = ?
Now
F = ma
7.5 = m * 15
m = 7.5/ 15
Mass = 0.5 kg
D. 200%
if 8 is a whole (100%) and 16 is twice of that, you can conclude that her speed increased by 200%
Answer:
The exact volume of a cone is 10 yd³.
Step-by-step explanation:
Given:
Height of cone (h) is 6 yd and base (b) is 5 yd.
Now, to get the volume we need to find the radius.
So, to find radius we put the formula of base:
Let the radius be
Base=


Dividing both sides by π and using square root on both the sides:




Now, putting the formula for getting the volume (v) of cone:
Volume = 


Substituting the value of
from equation (1), we get:

yd³
Volume of cone is 10 yd³
Therefore, the exact volume of a cone is 10 yd³.
