Answer:
(A) Take half the area of the whole circle.
Step-by-step explanation:
A semi-circle is half of a circle, thus the area of circle is given by:'
Area of circle=
, where r is the radius of the circle.
Since, A semi-circle is half of a circle, therefore area of the semi circle is also half of the circle, therefore
Area of semi circle=
Thus, the area of the semi circle can be found by taking half the area of the whole circle.
The answer to this point. is to add then multiple. 1 year
Answer:
4.8ft
Step-by-step explanation:
Let x be the length of the side of the hot tub. Ricardo wants the pool's sides to be 5 times as long, so

Answer:
B
Step-by-step explanation:
Euler's formula tells you that ...
cos(θ) +sin(θ)·i ≡ e^(i·θ)
__
So, for θ = 90° (= π/2 radians), this is ...
cos(π/2) +sin(π/2)·i = 0 +i = i = e^(i·π/2) . . . . . matches choice B
