<em>a. 2√21 units</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<u><em>Area formula</em></u>
<em>A = π·r²</em>
<em>84π = πr²</em>
<em>r² = 84π/π</em>
<em>r² = 84</em>
<em>r² = 2²×3×7</em>
<em>r = √2²×3×7</em>
<em>r = 2√3×7</em>
<em>r = 2√21</em>
<em>Good luck !</em>
First we raise both members of the equality to the square:
(√-4x) ^ 2 = (100) ^ 2
Then, we solve:
-4x = 10000
We cleared x in the last instance
x = 10000 / (- 4)
x = -2500
answer:
the solution of √-4x=100 is
A) x = –2500
9^2pi is 81pi for the total region. 6^2 is 36pi for the unshaded region. Subtract those 2 values to find the area of just the shaded region
Where is the table i dont see it
Answer:
base 48 X 48 = 2304
triangles 0.5 X 48 X 25=600
600 X 4 = 2400
2400 + 2304 = 4704 squared inches
