The radius of a circle is 18 yards. What is the circle's area?<br> Use 3.14 for ​.
IrinaVladis [17]

Solution:

<u>We know that:</u>

  • Radius: 18 yards
  • πr² = Area of circle
  • π = 3.14

<u>Finding the area of the circle:</u>

  • (π)(r²) = Area of circle
  • => (3.14)(18²) = Area of circle
  • => (3.14)(324) = Area of circle
  • => Area of circle = 3.14 x 324 = 1017.36 yards²

Solve the equation and check the solution.
777dan777 [17]

Answer:

a = 4

Step-by-step explanation:

Here, we want to write and solve the given equation

a - 2.5 = 1.5

a = 2.5 + 1.5

a = 4

To check, we simply substitute a = 4

That would be;

4-2.5 = 1.5

This is correct

Decide whether the sequence 4,10,20,34,52 ....... is a linear model,
Alecsey [184]

Answer:

Lineal.

Step-by-step explanation:

To determine if the sequence 4,10,20,34,52 ....... is a linear model, a quadratic model or a cubic model, the following mathematical logical reasoning must be carried out:

4 to 10 = +6

10 to 20 = +10

20 to 34 = +14

34 to 52 = +18

Thus, we can see at a glance that the sequence increases 4 numbers in each digit, adding first 6, then 10, then 14 and so on, with which the next numbers in that sequence should be 74 (+22), 100 ( +26), 130 (+30), 164 (+34), and so on.

Therefore, since there is no quadratic or cubic relationship, the sequence is linear.
