The base of a cone is a circle.
The area of a circle is
.
Thus, the area of the base of a cone
.
The derivation of the formula for the area of a circle involves a bit of calculus, but if you'd like, I can walk you through it.
If you want to find the loan for 2 years then you are right.Moreover in most of the cases you need t pay the interest too.But in this cases interest rate is not mentioned.
Area of circle = πr²
Area of circle = π(4÷2)² = 12.57 cm²
Scientific notation is a number greater than 0 and less than 10 multiplied by 10 to a power. The expression will be equal to the number given.
91007500
We move the decimal place first so that the number is within our range:
9.1007500
Then we count how many places we moved the decimal. In this case we moved it to the left 7 times, so our exponent of 10 will be 7
Therefore in scientific notation it is 9.1007500 x 10^7
Some teachers prefer to have scientific notation rounded off to the nearest 10th place, so that would be:
9.1 x 10^7
