When doing that it will be B
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.
Answer:
0.012
Step-by-step explanation:
1.2*1/10*10
=0.012
STEP 1:
Add the fractions to figure how many hours he worked total
= 13/4 + 21/3 + 15/12
use common denominator of 12
= 39/12 + 84/12 + 15/12
= 138/12
simplify by 6
= 23/2 or 11 1/2 hours worked
STEP 2:
Multiply hours worked by $10.50 an hour
= 11 1/2 * 10.50
= 11.5 * 10.50
= $120.75 earned
ANSWER: Doug earned $120.75
Hope this helps! :)
OOOF! I would send a screenshot to my teacher if that happened. Online math sometimes does that. On maths watch I answered correctly but it doesn't accept the answer. Its so annoying
