Find the area of a sector, whose perimeter is 40 cm, and the radius is 8 cm.
Answers
Answer:
96 cm²
Step-by-step explanation:
From the question,
s = (2πr∅/360)+2r................. Equation 1
Where s = Perimeter of a sector, r = radius, ∅ = angle subtend by the sector at the center of the circle.
Given: s = 40 cm, r = 8 cm
Constant : π = 3.14.
Substitute into equation 1 and solve for ∅
40 = (2×8×3.14×∅/360)+(2×8)
40 = (50.24∅/360)+16
40-16 = 50.24∅/360
50.24∅/360 = 24
50.24∅ = 24×360
50.24∅ = 8640
∅ = 8640/50.24
∅ = 171.97°
Area of a sector (A') = ∅πr²/360
A' = 171.97×3.14×8²/360
A' = 95.997
A' ≈ 96 cm²

Answers
Answer:
B, 3 8/9
Step-by-step explanation:
It all comes down to equivalent fractions.
2 1/3 as an improper fraction is 7/3.
1 5/9 as an improper fraction is 14/9. 1/3 = 3/9.
With that being said 7 x 3 = 21 resulting in 21/9.
14/9 + 21/9 = 35/9.
35/9 as a mixed fraction is 3 8/9.
Which words represent a positive number?

It signifies a positive number, as described above, but it also means 'add' or 'plus'. For example 2+3 means 'two plus three' with a result of 5. Here, the plus-sign means addition. The same confusion happens with the minus ( – ) sign.
