Question

plzz answer me fast....​

Answer 1

Step-by-step explanation:

v=πr²h

given v=2310cm³ and h=15 cm

2310=3.14×r²×15

2310/15=3.14×r²

154=3.14×r²

154/3.14=r²

49=r²

r=√49

r=7

therefore radius of base is 7

Answer 2

Answer:

vol of cylinder is πrsq.h

h = 15

vol = 2310

2310 = 3.14 * r sq. * 15

2310/3.14*15 = r sq.

r sq. = 49

r = 7 (approximately)
