Let's convert this fraction to an equal fraction which holds a denominator of 100, since it is a power of 10.
Since the denominator can be multiplied by 5 to achieve 100, we can multiply the entire fraction by 5 to create an equivalent fraction that has a denominator of 100:
17/20 = (17*5)/(20*5) = 85/100
To obtain a decimal from this fraction, take the numerator and move its decimal one place to the left for every 0 in the denominator. Since our denominator has two zeros, we will need to move the decimal place on the 85 two places to the left.
This gives us an answer of .85, which can also be expressed as 0.85.

Answer:
The volume of the solid = 96π inches³
Step-by-step explanation:
* The solid in the figure is a cone
* Lets revise the rule of the volume of the cone
- The volume of the cone formula is:
V = (1/3) × area of the base × its height
∵ The base of the cone is shaped circle
∵ Area of the circle = π r²
∵ The length of the radius = 6 inches
∴ The area of the base = π (6)² = 36π inches²
* Now we can find the volume of the cone
∵ The length of the height of the cone = 8 inches
∴ V = (1/3) × 36π × 8 = 96π inches³
* The volume of the solid = 96π inches³
