x = 5.87 cm

Step-by-step explanation:

The triangle shown is a right triangle with congruent legs.

That makes it a 45-45-90 triangle.

The ratio of the lengths of the sides of a 45-45-90 triangle is

1 : 1 : √2

The length of either leg is hypotenuse/√2.

8.3 cm / √2 = 5.87 cm

x = 5.87 cm

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
