Answer:
Answer is 15√4 cm...
Step-by-step explanation:
I Have Trise A lot For This ANSWERS..
Here The Formula Is
Volume of cylindrical bucket = volume of conical heap
πR²H = ⅓πr²h
Here 'π' get cancelled.. 15² x 28 = ⅓ x r² x 21
225 x 28 / 21 = ⅓ x r²
225 x 4 / 3 = ⅓ x r²
225 x 4 / 3 x 3 / 1 = r²
225 x 4 = r²
√ 225 x 4 = r
r = 15√4 cm
