<em>Answer:</em>
<em>x ≅ 79.1</em>
<em>Step-by-step explanation:</em>
<em>10log(4x) = 25 </em>
<em>2log(4x) = 5 </em>
<em>log((4x)²) = 5 </em>
<em>(4x)² = 10⁵ </em>
<em>16x² = 100,000 </em>
<em>x² = 6,250 </em>
<em>x ≅ 79.1</em>
Find the length of the circumference:
Circumference = 2 x pi x radius
Circumference = 2 x 3.14 x 7
Circumference = 43.96 kilometers
90 degrees is 1/4 of a circle ( 360/4 = 90)
Arc length = 43.96/4 = 10.99 kilometers
