A cylinder has a volume of 48cm³ and a height of 9 inches what is the radius
​

0.82cm

Step-by-step explanation:

r = 0.81 cm

Step-by-step explanation:

Volume of a cylinder = πxr²xh

Volume = 48cm³

Height = 9 inches = 22.86 cm

Radius = ?

Using the above formula:

V = πr²h

r² = V / (πh)

r² =  48 / (π(22.86))

r² = 48/71.81

r² = 0.67 cm

Taking square root on both sides

r = 0.81 cm Ans

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
