Answer: 111.72 m^2 if they want round its 112
Is from O to C 14m
A=pixr^2
3.14x14^2= 615.44 m/2 half circle = 307.72
Area of triangle A= 1/2bh. .5x28x14=196
307.72-98=196= 111.72 m^2
Step-by-step explanation:
To answer that we just need to multiply the 2 numbers, and consider that 25% = 0.25
so we have:
25% of 395
= (25%)(395)
<span>= (0.25)(395)
</span>= 98.75
Answer:
~15 meters away
Step-by-step explanation:
c^2 = a^2+b^2
c^2 = 10^2+11^2
c^2 = 100+121
c^2 = 221
c = 
c = ~15
