Answer:
6
Step-by-step explanation:
From the pythagorean theorem the square lenght of hypotenuse is equal to sum of square lenght of base and side
(6.5)^2 = x^2 + (2.5)
42.25 = x^2 + 6.25 subtract 6.25 from both sides
36 = x^2 and x = 6
Answer:
Area of circle: 1662.57 cm
Circumference of circle: 144.57 cm
Step-by-step explanation:
Formula of area of circle:
pi x r2 or radius x radius
So, it's 22/7 x 23 x 23 = 1662.571429
Formula of circumference of circle:
2 x pi x radius OR
pi x diameter
Let's use the second method, to find diameter it is radius x 2 = 46
So,
46 x 22/7 = 144.5714286
