What is the surface area of a cylinder with a base radius of 3 ft and a height of 5ft

Solnce55 [7]

SA of a cylinder: 2 $\pi$ r² + 2 $\pi$ rh
r = radius of base
h = height of cylinder

Plug in 3 for r and 5 for h in the formula.
2 $\pi$ 3² + 2 $\pi$ (3)(5)
Use a calculator to solve.

2 $\pi$ 3² + 2 $\pi$ (3)(5) = 150.8 ft²

How many zeros in x^4 + 3x2 + 12

barxatty [35]

Answer:

We know that ,

Number of zeroes in a polynomial = degree of the polynomial

( degree of polynomial = the highest power in the polynomial )

therefore ,

$\bold\blue{number \:of \:zeroes \:of\: the \:given} \\\bold\blue{polynomial\: = \:4}$
