Crater Lake in Oregon is shaped like a circle with a diamet
Step-by-step explanation:
Answer:
![Area = 3\dfrac{15}{16}\ sq\ ft](https://tex.z-dn.net/?f=Area%20%3D%203%5Cdfrac%7B15%7D%7B16%7D%5C%20sq%5C%20ft)
Area is greater than
sq ft.
Step-by-step explanation:
Length of rectangular sign board =
ft
Width of rectangular sign board =
ft
Area of a rectangle is given by the formula:
![A = Length \times Width](https://tex.z-dn.net/?f=A%20%3D%20Length%20%5Ctimes%20Width)
To find the area, we are going to multiply
with
.
is greater than 1.
Therefore the multiplication will be greater than
.
Hence, we can say that area will be greater than
sq ft.
Area of the sign:
![A = 3\dfrac{1}{2}\times 1\dfrac{1}8\\\Rightarrow A = \dfrac{7}{2}\times \frac{9}8\\\Rightarrow A = \dfrac{63}{16}\\\Rightarrow A = 3\dfrac{15}{16}\ sq\ ft](https://tex.z-dn.net/?f=A%20%3D%203%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%201%5Cdfrac%7B1%7D8%5C%5C%5CRightarrow%20A%20%3D%20%5Cdfrac%7B7%7D%7B2%7D%5Ctimes%20%5Cfrac%7B9%7D8%5C%5C%5CRightarrow%20A%20%3D%20%5Cdfrac%7B63%7D%7B16%7D%5C%5C%5CRightarrow%20A%20%3D%203%5Cdfrac%7B15%7D%7B16%7D%5C%20sq%5C%20ft)
Answer:
x = 15 inches
Step-by-step explanation:
![a^{2} +b^{2} =c^{2} \\b^{2} = c^{2} - a^{2} \\b^{2} = (25 inches)^{2} - (40 inces/2)^{2} = \sqrt{225} = 15 inches](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D%20%5C%5Cb%5E%7B2%7D%20%3D%20c%5E%7B2%7D%20-%20a%5E%7B2%7D%20%5C%5Cb%5E%7B2%7D%20%20%3D%20%2825%20inches%29%5E%7B2%7D%20-%20%2840%20inces%2F2%29%5E%7B2%7D%20%3D%20%5Csqrt%7B225%7D%20%20%3D%2015%20inches)
