How would i solve this does anyone know?

KATRIN_1 [288]

You need to use pythagorean’s theorem. so a^2+b^2=c^2.

in this case it would be 6^2+8^2=c2

36+64=100

the square root of 100 is 10

x=10

A cylinder has a base diameter of 16cm and a height of 19cm. What is its volume in cubic cm, to the nearest tenths place?

elena-14-01-66 [18.8K]

Answer:

V = 3216.9 $cm^{3}$

Step-by-step explanation:

Volume of a cylinder = π $r^{2}$ h

We are given diameter, 16cm, and half of it is the radius

r = 8cm

h = 19cm

Substitute the values into the equation

V = π * $8^{2}$ * 19

V = 3216.9 $cm^{3}$
