Step-by-step explanation:
since the pond is circular, its area will be πr².
a= πr², where r= 7ft
1 m ≈ 3.2808 ft
3.2808 ft ≈ 1 m
1 ft = 1/3.2808
7 ft = 1/3.2808 * 7
= 2.13362.. m
a= πr²
a= 3.14 * ( 2.13362...)2
a= 3.14 * 4.5523596...
a= 14.2944..
a= 10.0 m² (rounded to nearest tenth)
is the question right?
Answer: 292 tiles
Step-by-step explanation:
To find the number of tiles needed , we need to know the area of the hexagonal tiles and also the area of the room.
<u>Area of hexagon</u>
The area of hexagon is given as :
Area =
Where a is the length of side.
Therefore:
A =
A = X 400
A = (400 x 3 x ) / 2
A =
A = 1039.23
Also to find the area of the room , we must first convert from m to cm
6.25 m = 6.25 x 100 cm
6.25m = 625 cm
4.85m = 485cm
Therefore: Area of the room = length x breadth
Area = 625 x 485
Area = 303125
Therefore , the number of tiles needed = area of the room / area of hexagon
Number of tiles = 303125/ 1039.23
N = 291.6823032
Therefore , the number of tiles needed ≈ 292
Answer:
Straight line graph with positive gradient (slope)
y-intercept: (0, -3)
x-intercept: (12, 0)
Step-by-step explanation:
is a linear function
The line intercepts the y-axis when x = 0:
Therefore, the y-intercept is (0, -3)
The line intercepts the x-axis when y = 0:
Therefore, the x-intercept is (12, 0)
The point is now at (3,0).
After 7 days means the temperature has changed 7 times so
7 x (-1.2)
=-8.4°
so the temperature decrease 8.4 degree
