For this case we have the following expression:
Let's evaluate the expression for some values of x.
We have then:
For x = 1:
For x = 2:
For x = 3:
For x = 4:
For x = 5:
Answer:
The value of the expression in ordered pairs is:
- (1,8)
- (2.6)
- (3,4)
- (4.2)
- (5.0)
Answer:
2 and 5 are factors of 10
Answer:
116 cm²
Step-by-step explanation:
Shaded Area = area of the larger circle - area of the smaller circle
Area of the larger circle = πr²
Where,
r = 6.5 cm
Area = π*6.5² = 42.25π cm²
Area of smaller circle = πr²
Where,
r = 2.3 cm
Area = π*2.3² = 5.29π cm²
✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264
Area = 116 cm² (3 S.F)
These are important and common formulas; better learn them!
The volume of a cube of side length x is x^3.
The cross-sectional area is x^2.
The total surface area is A = 6x^2.
