If your not busy

Answer 5

okay

Answer 6

# 13

if you multiply all sides by k, then you multiply the area by k^2

Answer 7

# 14

the height of can A is 3 (you cut the other height 6 in half)

So r = 2, h = 3

Use the formula

LSA = 2*pi*r*h

to find the lateral surface area

Answer 8

so 14 is 37.68

Answer 9

And for 13 whats K @jim_thompson5910

Answer 10

14 is incorrect

Answer 14

for #13, k = 8 since you're multiplying every side by 8

Answer 15

ok last one

Answer 16

the diameter of the ball is 20 cm, so the height of the cylinder is 20 cm

the radius of the cylinder is 20/2 = 10 cm

so,

r = 10
h = 20

Answer 17

now use the formula

V = pi*r^2*h

Answer 18

6280?

Answer 19

good

Answer 20

is 13 96

Answer 21

no, if you multiply all sides by k, then you multiply the area by k^2

Answer 22

k = 8

Answer 23
