Answer:
Solution given:
The area of a circle =80.86cm²
we have:
The area of a circle =πr²
substituting value of area of circle we get
80.86cm=3.14*r²
dividing both side by 3.14
80.86/3.14=3.14*r²/3.14
25.75=r²
doing square root on both side

r=5.07cm
<u>The</u><u> </u><u>length</u><u> </u><u>of</u><u> </u><u>radius</u><u> </u><u>is</u><u> </u><u>5</u><u>.</u><u>0</u><u>7</u><u>cm</u>
-4x +4 = -3x + 31
4 - 31 = -3x + 4x
-27 = x
Answer:
1E-6 m^3 or 0.000001 m^3
Step-by-step explanation:
1cm^3 = 1cm*1cm*1cm
1m^3 = 100cm*100cm*100cm = 1000000 cm^3
1/1000000 = 1E-6 m^3
