Answer:
113.1 cubic inches
Step-by-step explanation:
The volume of a cylinder is given by the formula:
Where
V is the volume
r is the radius
h is the height
Given, h = 9 and r = 2, we substitute and find the volume:
We need answer to nearest tenth, that is 1 decimal place, so we round of the answer as:
113.1 cubic inches
<h2>15 58</h2>
Step-by-step explanation:
BD = DC = 1/2 BC ---> AD is median ( because in equilateral triangle altitude equals to median )
so, therefore
AB = 18 (given)
BD = 1/2 BC
BD = 1/2 × 18
BD = 9
AB² = AD² + BD² ---( by pythagoras theorm)
18² = AD² + 9²
324 = AD² + 81
324 - 81 = AD²
243 = AD²
then,
AD = √243
AD = 15 58
