First let's convert 30 miles to feet.
30 x 5,280 = 158400
Now let's find how many feet the first person runs per minute.
158400/60 = 2640
The first person runs 2,640 feet per minute, and the second person runs 3,520 feet per minute.
Since the second person runs fast, let's find by how many miles per hour they're faster than the first person.
3520-2640 = 880
How many miles is 880 feet?
5280/880 = 0.17
The second person runs faster by 0.17 miles per hour.
Hope this helps! :)
The answer is ( 1/3)/4/1/4=x
10,000 is the correct answer
Answer:
-4
Step-by-step explanation:
2/5 times -10 = -4
Answer:
Step-by-step explanation:
Diameter of cone=14 cm
so, Radius of cone= 7cm
Height of cone= 8cm
∴ Volume of cone= 1/3*pi*r^2*h
=1/3*pi*49*8 cm^3
In Sphere, External Radius R=5cm
Let, Internal Radius = r
Volume of Sphere = External Volume- Internal Volume
= 4/3*pi*R^3-4/3*pi*r^3
=4/3*pi[R^3-r^3]
=4/3*pi[5^3-r^3]
But During Conversion Volume Remains Same
So, Volume of Sphere=Volume of Cone
4/3*pi[125-r^3]= 1/3*pi*49*8
4[125-r^3]=49*8
[125-r^3]=49*2
r^3=125-98
r^3=27
so, r =3 cm
Internal Radius= 3cm
So, Internal Diameter=3*2= 6cm
