The area of a circle of diameter d is given by
.. A = (π/4)d^2
so the area of a semicircle with that diameter will be half that.
The banner has area
.. (26 in)^2*(1 +π/8) ≈ 941.33 in^2
Answer:
No. If you multiply 138 x 7 you will get 966. Which isn't a very close estimate at all.
<span> The geometric mean of two non negative numbers x and y is √(xy). (mean square root of XY)
So the geometric mean of 2/3 and 27/40 is
√(2/3 * 27/40)
= √(54 / 120)
= √(27 / 60)
= √(9 / 20)
= 3 / √20
= 3 / 2√5
= 3√5 / 10. </span>
Answer:
x = 25
y = 65
Step-by-step explanation:
(I did it on Math Nation)
180 = 130 + 2x
50 = 2x
x = 25
180 = 50 + 2y
130 = 2y
y = 65
Answer:
68 and 68
