Answer:
5. 50.3 m²
6. 113.1 cm²
7. 102.1 yards²
8. 50.3 yards²
9. 452.2 ft²
10.379.8 ft²
Step-by-step explanation:
Area of a circle = nr²
The circumference of a circle = 2nr
n = pi = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = diameter / 2
5. (22/7) x 4² = 50.3 m²
6. (22/7) x 6² =113.1 cm²
7. radius = 11.4/2 = 5.7 yards
(22/7) x 5.7² =102.1 yards²
8. radius = 8/2 = 4 yards
(22/7) x 4² = 50.3 yards²
9. 2nr = 75.4 yards
2 x (22/7) x r = 75.4
to find r, divide both sides of the equation by 2 and 7/22
r = 12 ft
Area = (22/7) x 12² = 452.2 ft²
10. 2nr = 69.1 yards
2 x (22/7) x r = 69.1
to find r, divide both sides of the equation by 2 and 7/22
r = 10.99 ft²
Area = (22/7) x 10.99² = 379.8 ft²
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Considering the given graph of the function, we have that:
- Function Notation: f(1) = -3.
- Verbal statement: If x is equal to -1, then the value of f(x) is equal to -3.
<h3 /><h3>How to find the numeric value of a function looking at it's graph?</h3>
To find the numeric value of the function, we get a value of x(horizontal axis), and then look at the corresponding value y(vertical axis), then y = f(x).
In the graph of this function, we have that when x = 1, y = -3, hence:
- Function Notation: f(1) = -3.
- Verbal statement: If x is equal to -1, then the value of f(x) is equal to -3.

Remember in a geometric sequence you multiply if it is increasing if it is decreasing it is a number less than 1
Ina arthritic sequence you add if it is increasing if it is decreasing you add by a negative number
This sequence is geometric it is being multiplied by 1/2
