Answer:
his mass before the race was 68.5kg
Step-by-step explanation:
let,his mass before the race was 'x'
By question,
x-2% of x =67.13
or,x- 2x/100=67.13
or, 98x/100=67.13
or,98x=67.13×100
or,98x=6713
or,x=6713÷98
or,x=68.5
thus,his mass before the race was 68.5 kg
The answer is 12 because it’s a circle and that dot in the middle is the radius. so the radius is 6 which mean the diameter is 2x that making it 12
Answer:
The answer is 16π
Step-by-step explanation:
Firstly , you should keep in mind the the Area of a circle is :πr squared.
Also the diameter is TWICE as much as the radius!
So , 8/2=4 ( radius)
Then , we do 4 x4 ( r squared) =16.
16xπ=16π.
Therefore, answer is 16π!
