Answer:
1661.06 cm²
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 11.5 cm
Size of synthetic leather needed =?
To know how many square centimetres of synthetic leather needed to cover the ball, we shall determine the area of the ball. This can be obtained as follow:
Radius (r) = 11.5 cm
Pi (π) = 3.14
Area of ball =?
The shape of a ball is spherical in nature. Thus, we shall apply the formula for calculating the area of a sphere. This is illustrated below:
A = 4πr²
A = 4 × 3.14 × 11.5²
A = 4× 3.14 × 132.25
A = 1661.06 cm²
Thus, 1661.06 cm² of synthetic leather needed to cover the ball.

Answer:
Hello. Since there is one value of of y for every value of x in {(-1,1),(2,2),(0,0),(5,5)}, this would be a function.
Step-by-step explanation:
We can first change 4% to a decimal by dividing by 100:
Then we can multiply this by 3.5km:
So now we know that 4% of 3.5km is 0.14km.
