Answer:
50.24
Step-by-step explanation:
radius R = 2
SA = 4πR^2 = 4π*2^2 = 16π = 16*3.14 = 50.24
Answer:
<h2>The answer is 3.4</h2>
Step-by-step explanation:
The sequence above is an arithmetic sequence
So in order to find the common difference subtract the previous term from the next term
So we have
<u>Taking 9.4 and 6</u>
That's
9.4 - 6 = 3.4
<u>Taking 12.8 and 9.4</u>
12.8 - 9.4 = 3.4
<u>Taking 16.2 and 12.8</u>
16.2 - 12.8 = 3.4
Since the common difference is the same for any of the terms taken , the common difference is 3.4
Hope this helps you
Answer:
8 x^5 y^7
Step-by-step explanation:
Simplify the following:
4×2 x^2 y^3 x^3 y^4
Hint: | Combine products of like terms.
4 x^2 y^3×2 x^3 y^4 = 4 x^(2 + 3) y^(3 + 4)×2:
4×2 x^(2 + 3) y^(3 + 4)
Hint: | Evaluate 3 + 4.
3 + 4 = 7:
4×2 x^(2 + 3) y^7
Hint: | Evaluate 2 + 3.
2 + 3 = 5:
4×2 x^5 y^7
Hint: | Multiply 4 and 2 together.
4×2 = 8:
Answer: 8 x^5 y^7
