Answer:
B
Step-by-step explanation:
Use the pythagorean theorem
a² + b² = c²
a² + 63² = 65²
a² + 3969 = 4225
a² = 256
a = 16
x = 16 meters
Answer:
A≈254 cm^2
Step-by-step explanation:
The area of a circle is given by formula: π
r^2
π has a constant value of 3.14 And the radius of the circle is 9
c
m
the area= π
r^2 = 3.14 x (9)^2 cm^2
=
3.14
