Answer:
1. D) -4/3 or 4/3
2. A) -6 or 8
Step-by-step explanation:
First, solve for the radius of the sphere using the volume and the equation,
V = 4πr³ / 3
Substituting for the known values,
3000π m³ = 4πr³/3
The value of r from the equation is approximately 13.10 meters. The equation for the surface area is,
SA = 4πr²
Substituting the value of radius,
SA = 4π(13.10 m)² = 2157.74 m²
Therefore, the surface area is approximately 2157.74 m².
Its 1,000 because its 981 right so you have to use a line so you'll see where 981 is.
Answer:
28 miles in 1.4 hours in the city
Step-by-step explanation:
<u>On the highway:</u>
Time 
hours
Rate = 45 mph
Distance 
miles
<u>In the city:</u>
Time 
hours
Rate = 20 mph
Distance 
miles
The trip was 100 miles long, then
Distance on the highway 
miles
Distance in the city 
miles
