What is the volume of a cone with a height of 9.5 inches and a radius of 8 inches? Cone V = 1 3 Bh 1. Rewrite the formula for th
Nesterboy [21]

Answer:

636.4 in³  

Step-by-step explanation:

Volume of a cone is given by:

V = \frac{1}{3}\pi r^2 h

where r is the radius of the base of the cone and h is its height.

It is given that, the radius of the base of the cone is, r = 8 in

The height of the cone is, h = 9.5

\Rightarrow V = \frac{1}{3} \times 3.14 \times (8)^2 (9.5) = 636.4 in^3

Thus, the volume of the cone is 636.4 in³

vivado [14]
The falcon can fly 322,000 meters per hour.

1 kilometer is 1000 meters, meaning you would multiply 322 by 1000 equaling 322,000.

ben earns $9 per hour and $6 for each delivery he makes. he wants to earn more than $155 in an 8-hour workday. what is the least
Ymorist [56]
First find out how much he makes in 8 hours (9x8=72). Then subtract 72 from 155 (155-72=83). Then divide 83 by 6 (83/6=13.8333). Since 83 is not evenly divisible by 6, and since he can't deliver .8333 of a delivery, we would round up, giving us 14). Ben would need to make 14 deliveries in 8 hours to make more than $155 :) Hope this helps you :)
