Answer:
12 3/20 is the simplest form
if the minute hand of the <u>circular clock</u> is 28 inches, that simply means its radius is 28.
![\bf \textit{area of a circle}\\\\A=\pi r^2~~\begin{cases}r=radius\\[-0.5em]\hrulefill\\r=28\end{cases}\implies A=\pi 28^2\implies A=784\pi](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Barea%20of%20a%20circle%7D%5C%5C%5C%5CA%3D%5Cpi%20r%5E2~~%5Cbegin%7Bcases%7Dr%3Dradius%5C%5C%5B-0.5em%5D%5Chrulefill%5C%5Cr%3D28%5Cend%7Bcases%7D%5Cimplies%20A%3D%5Cpi%2028%5E2%5Cimplies%20A%3D784%5Cpi)
so it covers that much in 1 rotation, so in 4 rotations that'd be 4(784π) => 3136π.
Answer:
Since 6X2 + 6Y2 = 13 xy
-- 6X2 / XY + 6Y2/XY =13
---> 6 X/Y + 6 Y/X =13
6a + 6/a =13
---> 6a2 + 6 =13a
---> 6a2 -13a +6 =0
---> 6a2 -9a - 4a +6 =0
---> (2a-3) (3a-2) =0
2a-3 = 0
a= 3/2
So the Ratio will be = 3:2
Answer:
Step-by-step explanation:
The area here is 2 triangles and 3 rectangularso the total area is the sum of all areas area of triangle = 0.5 * base * height = 0.5 * 4 * 3 = 6 ft^2 the area of the rectangular 1 = 5 * 7 = 35 ft^2 the area of rectangular 2 = 4 * 7 = 28 ft^2 the area of rectangular 3 = 3 * 7 = 21 ft^2 so the total surface area = 2(6) + 35 + 28 + 21 = 96 ft^2
