Answer:
Step-by-step explanation:
Since area of a circle is pi.r^2
We know that diameter is 20
Radius is half of diameter
So it becomes
Pi.(d/2)^2
So pi.(40/4) is the area of this circle.
Or 40pi/4
Answer:
Step-by-step explanation:
1/2+1/3 L.C.M = 6
7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
<span>A healthy human body is approximately 18% carbon, so to determine how many pounds of carbon a 200lb body contains, compute 200lbs X 0.18 = 36 pounds. To convert 36lbs to kilograms, multiply by the conversion factor 0.454. Therefore, 36lbs X 0.454 = 16.344 kg.</span>
