Answer:
127.17 cm²
Step-by-step explanation:
- Area of a semicircle: 1/2*π*r²
- π (pi) = 3.14
- r (radius) = d (diamater) / 2 => 18/2 = 9 cm
A = 1/2*π*r²
A = 1/2*3.14*9²
A = 1/2*3.14*81
A = 3.14*40.5
A = 127.17 cm²
Therefore, the area of the semicircle is 127.17 cm²
Hope this helps!
Answer:
A = (0, -8)
Step-by-step explanation:
B = (A+C)/2 . . . . the midpoint is the average of the end points
A = 2B -C = 2(-3, -5) -(-6, -2) . . . solve for A, substitute point values
A = (0, -8)
The value of the land after 11 years will be $2,903,175.
A=2(LW+LH+WH)
A=2((7/8)(1/3)+(7/8)(2/5)+(1/3)(2/5))
A=2(7/24+14/40+2/15)
A=14/24+28/40+4/15
A=7/14+7/10+4/15 210
A=(105+147+56)/210
A=308/210
A=(210+98)/210
A=1 98/210
A=1 7/15
