Let the distance be x,
x÷4 = (×÷8)+1 ...multiply both sides by 4
x= 0.5x+4
0.5x=4
x=8
Time taken to walk=8÷4=2hours
Answer: 12 minutes
Step-by-step explanation:
7 km ........ 4 minutes
21 km ...... ?
21/7 x 4= 12 minutes
Answer:
56
Step-by-step explanation:
14/12 = d/48
48 / 12 = 4 x 14 = 56
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
The volume of a cone is 8003π cubic yards. The height is 8 yards. Find the radius.
<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
Height (h) of a cone is 8 yards. (Given)
We have to find the radius (r) of a cone.
Now,
<u>A</u><u>T</u><u>Q</u> ,
πr²h = 8003π
r²h = 8003 [ ' π ' is cancelled from both sides ]
r² × 8 = 8003
r² =
r² =
r² = 3001.125
r =
r = 54.78
