Question

VG=12.2 in. PG=13.1 in.

Answer 1

we know that

the figure VGP is a right triangle

VP-------> is the radius of the circle

so

Applying the Pythagoras Theorem

VP²=VG²+PG²---------> VP²=12.2²+13.1²-------> VP²=320.45-----> VP=17.9 in

radius is equal to VP

so

r=17.9 in

therefore

the answer is

the radius of the circle is 17.9 in
