Question

Please help and dont answer for points. Thx a bunch :)

Answer 1

HL is the radius which is half of the diameter....lso 24/2 = 12

r = 1/2(121) is the answer for this one since radius is 1/2 of the diameter

Answer 2

The first one is B - 12 in, because HL is half the length of HK, and half of 24 is 12.

The second one is also B - 1/2 (121) because the radius is half the diameter.

Hope this helps!
