Answer:
<h3>Area of a circle= πr²</h3><h2>50.24 = 3.14 *r²</h2><h2>r²= 50.24/3.14</h2><h2>r² =16</h2><h2>r= √16</h2><h2>r = 4</h2>
Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
3x² = 147
x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
√a = a¹/² so (x²)¹/², and (x²)¹/² =
x²×¹/² = x, therefore the solution is
x = +/- 7.
It would be heads 3 and 1/3 of the time and tails 6 and 2/3 coming to an outcome of 10
Ia=5/2*9.3^2(5+2--5)
a=665.47unit ^2
which then means 663.1
Answer:
a = -1,6 b = 1,11 c = 4,11 .
