Question

a well 7m in radius 22.5m deep to be dug. the soil thus obtained is spread over a rectangular field of side 22m×15m to make a platform.how high will be the platform?​

Answer 1

Answer:

10.49m

Step-by-step explanation:

here firstly volume of the well will be:

area×deept of well

so it will be

volume=pi×7×7×22.5

volume=3463.60

this volume is used to make a rectangular volume

so for findings height we will equate both the volumes

3463.60=h×22×15

from here you will get h as 10.49m
