Answer:

3.98 cm, 602.18 cm²

Step-by-step explanation:

Given:

r= 8 cm
V= 800 cm³

To find:

h = ?
S = ?

Solution:

V = πr²h
h = V/πr² = 800/(π8²) = 3.98 cm
S = 2πr (r+h) = 16π(8+3.98) = 602.18 cm²

Kobotan [32]

Answer:

$x+3y=-27$

Step-by-step explanation:

We are given that

$y=(-\frac{1}{3})x-9$

We have to find the standard form of given equation

$y=\frac{-x-27}{3}$

$3y=-x-27$

By using multiplication property of equality

$x+3y=-27$

We know that

Standard form of equation

$ax+by=c$

Therefore, the standard form of given equation is given by

$x+3y=-27$
