Pls solve this question it's urgent ​

Answer 1

Answer:

$formula = 2 \: \pi \: r \: (h + r)$

160π = 2π x 5 ( h+ 5)

160π = 10π (h+5)

160π/10π = (h+5)

16 = h+5

16-5 h

11 = h

Answer 2

Answer:

16 cm

Step-by-step explanation:

S.A formula of a cylinder = 2(pi) * r * h

since we know the S.A, we're gonna substitute it and the radius

- 160(pi) = 2 (pi) x 5 x h

160(pi) / 2(pi) x 5 = h { you take 2 (pi) x 5 to the opposite side, so instead of multiplication, it will change into division...ok?

so know you can cancel the (pi) and be left with = 160/10

= 16 cm
