Hello here is a solution :
<span> the radius of the circle is OA A(5;-12) and O (0;0)
OA= </span><span> square root ((5-0)² + (-12-0)²)
</span> = <span> square root (25+144)
</span> = <span> square root(169)
</span> OA = 13
Answer:
(5490-650) ÷ 22 = Y
Step-by-step explanation:
You'd use the equation a^2 + b^2 = c^2 (**** ^2 means squared****)
a = 60
b = 11
c = ?
60^2 + 11^2 = c^2
3600 + 121 = c^2
3721 = c^2
then just square root 3721 and c^2
c = 61 feet
