The surface area of a sphere is A = 4 π R² .
Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.
Circumference = π (diameter)
Divide each side by π : Diameter = circumference / π
Radius = 1/2 diameter: Radius = circumference / (2 π)
Area = 4 π R² =
4 π (circumference/2π)² =
4 π (circumference)² / 4 π²
Divide top and bottom by 4π : Area = (Circumference)² / π
Circumference = 37.68 units
Area = (37.68)² square units /π =
<em>451.93 square units</em>
Answer:
B.
Step-by-step explanation:
Answer:
D. y=5x+2
Step-by-step explanation:
The y int. is 2, and the slope is 5/1. If you plug that into a calculator, you can see the slope being steep.
The value of y in the diagram wiuld be four. think about it. it would be four because how many pieces are in a triangle? mmm it is 3 in a triangle so if i add up one i would have to add 3+1=4 and that is how i got the answer
THANKS TO ME U NOW KNOW THE ANSWER :)
Hello there! 6.487 rounded to the nearest hundredths place is 6.49 and 2.049 rounded to the hundredths place is 2.05. The sum of these numbers is 8.54.
Remember: If the number value after the value you are rounding is equal to or greater than 5, round up. If it is less than 5, round down.
With this in mind, let's round the numbers:
First: 6.487 rounded to the hundredths place would be 6.49, since 7 is greater than 5.
Second: 2.049 rounded to the hundredths place would be 2.05, since 9 is greater than 5.
Next, we will add the numbers together
2.05 + 6.49 = 8.54.
So, this is our final answer. I hope this answers your question & have a great day! :)
