You should write numbers in as many ways as you possibly can to make new connections in your brain. Knowing how to write numbers in many different ways can help you solve complex problems more easily. Doing this can also reinforce the mathematical principles and logic you have memorised.
Writing one in many different ways:
1=1/1=2/2=3/3=4/4=(-1)/(-1)=(-2)/(-2)
=1.0=1.00=1.000=(1/2)+(1/2)=(1/3)+(1/3)+(1/3)
=(1/4)+(1/4)+(1/4)+(1/4)
Writing a half in many different ways:
1/2=(1/4)+(1/4)=(1/6)+(1/6)+(1/6)
=(1/8)+(1/8)+(1/8)+(1/8)=4*(1/8)
=2/4=3/6=4/8=5/10=0.5=0.50
etc...etc...
so we have a table of values, with x,y coordinates, so let's use any two of those points to get the slope of the table and use the point-slope form to get its equation

The area of any circle is (pi) x (radius)² .
The area of the WHOLE circle in the question is
(pi) x (2.5 cm)²
= (pi) x (6.25 cm²) .
The full circle is made by 360° of central angles.
90° of central angle makes a pie-wedge (sector)
that's exactly one fourth of the circle, so its area
is one fourth of the area of the whole circle.
Area = (1/4) (pi) (6.25 cm²)
= (0.25) (3.14) (6.25 cm²)
= 4.906 cm² .
Rounded to the nearest tenth: 4.9 cm² .
Answer:
153 In.
Step-by-step explanation:
Add the area area of each of the individual shapes together
Regular hexaganol has six sides. since the perimeter of it is 72, we need to divide it to 6 to get the length of the one side which is attached to room A. 72:6=12 One side of a Hexaganol is 12, and it is attached to room A, which is quadratic. so it has equal sides, which is 12. to know the <span>square feet of carpet to cover the floor of Room A you need to: s=a2=12*12=144</span>
