Question

If V= 43 πr³, find (i) the value of "V" when r = 7 (ii) the value of "r" when V = 256
with solution please​

Answer 1

Answer:

V=43(Pie)r^3

Step-by-step explanation:

to find r make r subject

so therefore

V/43(pie)=r^3

to remobe cubic from r cube root both side

so therefore

cube root(V/43(pie)=r

V=256

pie=22/7

so r=(256÷43× 22/7)
