Answer:
D. 314 m²
Step-by-step explanation:
Area of circle= π r²
Radius = r = 10 meter
By putting radius in formula we get
area = 314.159 m² and nearest square meter is 314 m²
If you’re trying to find the area of the step:
A=lwh
A=20•15•8
A=2,400 cubic inches
or 2,400 in ²
Answer:
7.5 jars
Step-by-step explanation:
There are 25 students in the art class.
Mr Jones is planning that for the project, each of the 25 students will need 0.3 jar of paint.
The amount of paint Mr Jones needs for this project is therefore the product of the number of students in the class by the amount of paint each student needs.
That is:
25 * 0.3 = 7.5 jars of paint
Mr Jones needs 7.5 jars of paint for the art project.
The approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.
<h3>What is Exponential equation?</h3>
In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.
Here, given equation; (we are using n in place of t)
-5.e¹⁰ⁿ = -30
On dividing -5 both sides, we get
-5.e¹⁰ⁿ/-5 = -30/-5
e¹⁰ⁿ = 6
Taking 'ln' on both side, we get
10n = ln 6
n = (ln 6)/10
n = 1.791759/10
n = 0.179
Thus, the approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.
