Answer:
9
Step-by-step explanation:
Use the Pythagorean Theorem which states
a² + b² = c²
then plug in your given terms
a² + 5.6² = 10.6²
find the squares
a² + 31.36 = 112.36
subtract 31.36 from 112.36 to find your a²
a² = 81
then find the square root of 81, which is 9 becuase 9 x 9 is 81
Answer: 147 cm²
Step-by-step explanation:
Since it says to use 3 for pi, and the radius is given to us (7 cm), we will plug in and solve for the area.
A = πr²
A = (3)(7)²
A = 147 cm²
