Answer:
in a day (3/4)÷7=3/28
in a year (3/28)×365=39.107
100-9(2+6)=100-9(8)=100-72=
so the answer is 28
The cube has 6 this same faces.
Therefore the surface area is equal 6 · 7cm² = 42cm²
Answer:
25.1 inches
Step-by-step explanation:
Radius of the circle = 4 inches
We have to calculate the value of Circumference of the circle.
The formula to calculate the circumference is:
Circumference = 2πr
We have to use π = 3.14, as said in the question:
So using the values, we get:
Circumference = 2 x 3.14 x 4 = 25.12 inches
Number of decimals in radius is zero, so we have to round the answer to one decimal place as said in the question.
Therefore, the circumference of the circle rounded to one decimal place will be 25.1 inches
