Please solve number 4

Step 1: Formula for volume of cylinder.

$V = \pi r^{2} h$

Step 2: Substitute $r = 5$ cm, $h = 10$ cm, $\pi = 3.14$.

$V = 3.14 \times (5)^{2} \times 10~cm^{3}$

Step 3: Calculate $(5)^{2}$.

$(5)^{2} = 25$

$V = 3.14 \times 25 \times 10~cm^{3}$

Step 4: Calculate $3.14 \times 25$.

$3.14 \times 25 = 78.5$

$V = 78.5 \times 10~cm^{3}$

Step 5: Simplify.

$V = 785~cm^{3}$

Final answer: 785 cm^{3}
