The area of a semicircle is (πr^2)/2, with r being the radius
the radius is going to be the diameter diced by two: 49/2 = 24.5
now, plug in and solve
(π24.5^2)/2 = 600.25π/2 = 300.125 π
π is roughly equivalent to 3.14, so we can multiply to simplify
area = 942.87
Answer:
Fixed
x=5.66
Step-by-step explanation:
This is an around about way since it's not a right triangle.
lets call the segment line that bisects the lower right angle= M.
The two triangles created would be similar. So:
4/6=M/(x+3)
4x+12=6M
M=(4x+12)/6
and
(x+3)/(x+4)=M/6
(6x+18)=Mx+4M
M=(6x+18)/(x+4)
since M=M
(4x+12/6=(6x+18)/(x+4)
(x+4)(4x+12)=6(6x+18)
4x^2+12x+16x+48=36x+108
4x^2+28x+48=36x+108
4x^-12x-60=0
x^2-3x-15=0
Factor
(x+2.65)(x-5.66)=0
x=5.66

True. just like Texaschic101 said DV= M
H(10)=8(10)+10
h(x)=90
hope this helps
