I think: C. 109.9 inches;
Considering that the entire circumference is 2 \pi r a semicircle should be only: \pi r=3.14*35=109.9 in

If it were a complete circle, its circumference would be

             (π) x (diameter) = (π) x (2R)  =  70 π inches .

Since it's only half of the circle, the length of the curved part is

                              70 π / 2  = 35 π  =  <em>109.9 inches</em> .

Solve for n:<br> 3⁄5 · n = 6
garik1379 [7]

Answer:

n = 10

Step-by-step explanation:

Solve for n:

(3 n)/5 = 6

Multiply both sides of (3 n)/5 = 6 by 5/3:

(5×3 n)/(3×5) = 5/3×6

5/3×3/5 = (5×3)/(3×5):

(5×3)/(3×5) n = 5/3×6

5/3×6 = (5×6)/3:

(5×3 n)/(3×5) = (5×6)/3

(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:

n = (5×6)/3

6/3 = (3×2)/3 = 2:

n = 5×2

5×2 = 10:

Answer:  n = 10
