Length of circular track is:
L = 2*r*pi
He run 3/4 of it so length is:
L' = 3*2/4*r*pi = 3/2*r*pi
To calculate speed of his movement we use formula:
v = s/t where s = L' and t = 1 minute 45 seconds = 105 seconds
v = L'/t = 3*r*pi/2*105
v = r* pi/70
If we take that r = 1
answer
Answer:
1,177.5
Step-by-step explanation:
I have not done this is a while but the formula is v = 3.14 r^2 h
so 3.14 x 5^2 x 15
then 3.14 x 25 x 15
lastly multiply it all to get 1,177.5
Hope this helps <3
Step-by-step explanation:
yeah she be correct 2.1
Answer:
yes
Step-by-step explanation:
any number is a difference
The equation for volume of a sphere is pi(r)^3 This mean that the equation would be pi(11)^3 which equals 1331pi
