Answer:
then value of 7/2R is 0.10842627013
Step-by-step explanation:
by using Python theorem
EC²=EB²+BC²
EC²=4²+10²
EC²=16+100
EC=√116
EC=10.77
by by using Python theorem
AC=√AB²+BC²
AC=√10²+10²
AC=√100+100
AC=√200
AC=14.14
in triangle AFC
F is the midpoint of ∆ as it is made by intersection of two perpendicular line
base=FC=EC/2=10.77/2=5.38
height=AE=AB-BE=10-4=6
area of triangle=base × height
R= 5.38×6
R=32.28
then value of 7/2R
=7/2×32.28
=7/64.56
0.10842627013
