What is the value of x to the nearest tenth

5.4

Step-by-step explanation:

Notice that if you create a line that joins line 2.4 and line 9.6 you then form a right triangle with a hypotenuse equal to the radius. Then use the Pythagorean Theorem to solve for the radius:

(4.8^2)+(2.4^2)=C^2

23.04+5.76=C^2

28.8=C^2

√28.8=√C

5.4=C

so, converting firstly the mixed fractions to improper fractions and then "adding".
