The first figure, on left, is the composition of two areas, the area of a 7cm circle and the area of a 7 cm square so:
A=7^2+7^2π/4
A=49+49π/4
A=49(1+π/4) cm^2
A≈87.48 cm^2 (to nearest hundredth of a square centimeter)
...
The second figure is the area of a 15cm by 8cm rectangle minus the area of a 3cm circle so:
A=15(8)-3^2π/4
A=120-9π/4
A=120-2.25π cm^2
A≈112.93 cm^2 (to nearest hundredth of a square centimeter)
In scientific notation, a number is usually?.?*10^??
for example:
1.3*10^-2
To write it in standard notation you can simply multiply it out
for example:
0.013
The answer is 1/6 because 2/3-1/2 the command denominator is 6 so 2 goes in six 3 times then you do 3×1 =3 so you got 3/6 then you do 3 goes in 6 2 times then you do 2×2=4 and 4-3=1 so you get 1/6
