-20÷5(-3)+4(-2)(-1)-4²<br>step by step please and thank you!​

\huge \boxed{\mathbb{QUESTION} \downarrow}

\large \tt \: -20 \div  5(-3)+4(-2)(-1)-4  ^ { 2  }

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

\tt \: -20 \div  5(-3)+4(-2)(-1)-4  ^ { 2  }

Divide -20 by 5 to get -4.

\tt \: -4\left(-3\right)+4\left(-2\right)\left(-1\right)-4^{2}

Multiply -4 and -3 to get 12.

\tt \: 12+4\left(-2\right)\left(-1\right)-4^{2}

Multiply 4 and -2 to get -8.

\tt \: 12-8\left(-1\right)-4^{2}

Multiply -8 and -1 to get 8.

\tt \: 12+8-4^{2}

Add 12 and 8 to get 20.

\tt \: 20-4^{2}

Calculate 4 to the power of 2 and get 16.

\tt \: 20-16

Subtract 16 from 20 to get 4.

=  \boxed{\boxed{ \bf 4}}

What is the approximate volume of the cylinder use 3.14 for TT
Fynjy0 [20]
First we want to know the surface of the circle, which is
\pi {r}^{2}
with r representing the radius. In this case
\pi \times {8}^{2} =
64\pi

To find the volume of the cylinder we have to multiply this outcome with the height.
64\pi \times 25 =
64 \times 3.14 \times 25 =
5024
Hence, the volume of the cylinder is about 5024 cubic cm.
