What is the volume of a hemisphere with a radius of 61.9 m, rounded to the nearest

ZanzabumX [31]

Answer:

The volume of the hemisphere is 496741.6 m³

Step-by-step explanation:

The volume of an sphere is given by:

$V_{s} = \frac{4\pi r^{3}}{3}$

In which $\pi = 3.14$ and r is the radius.

An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So

$V_{h} = \frac{V_{s}}{2} = \frac{2\pi r^{3}}{3}$

In this question:

$r = 61.9$ . So

$V_{h} = \frac{2\pi (61.9)^{3}}{3} = 496741.6$

The volume of the hemisphere is 496741.6 m³

What are the truck ID’s of trucks that have carried small shipments. Small shipments are defined as those that weigh less than 8

Ivanshal [37]

Table for the question is attached in the picture below :

Answer:

SELECT distinct(TRUCK_ID), WEIGHT from SHIPMENT where WEIGHT < 800 ;

Step-by-step explanation:

The Structured query language (SQL) defined above, returns only the TRUCK_ID and Weight column from the shipment table as they are the only two columns listed after the select keyword. The condition is added using the WHERE keyword on the weight table, this filters the result returned to include only rows where the weight value is less than 800. The distinct keyword used alongside the TRUCK_ID column ensures that a certian TRUCK_ID value isn't returned more than once (Hence, it is used to avoid duplicates).
