Answer:
The value of x is 3.2 cm.
Explanation:
We know that the diameter of the circle is 9 2/5 cm. We also know that the diameter of a circle is twice the length of its radius. Therefore, we can write:
2(radius) = diameter
2(x + 1.5) = 9 \ 2/5
Multiplying both sides by 5 to get rid of the fraction, we get:
2(x + 1.5) * 5 = 9 * 5 + 2
10(x + 1.5) = 47
Dividing both sides by 10, we get:
x + 1.5 = 4.7
Subtracting 1.5 from both sides, we get:
x = 4.7 - 1.5
x = 3.2
Therefore, the value of x is 3.2 cm.
