Answer:
Depends on which answer they give you to answer. If you have the one I have which is *IRA contribution* then go for it!
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!
The coordinates would be multiplied by 3, as the scale factor is 3, and it is a dilation, so we know the size increases.
Answer: 0.6
Reason: 3 divide by 5 is 0.6
