El perímetro de una circunferencia es de 40π cm, y tiene un ángulo de 130°. Calcula el área del sector de dicha circunferencia.
Answers
Answer:
Area of sector = 144.4π cm²
Step-by-step explanation:
Given:
Perimeter of circle = 40π cm
Given angle = 130°
Find:
Area of sector
Computation:
Perimeter of circle = 2πr
⇒ 40π = 2πr
⇒ 40 = 2r
⇒ Radius r = 40 / 2
Radius r = 20 cm
Area of sector = [θ/360][π][r]²
⇒ Area of sector = [130/360][π][20]²
⇒ Area of sector = [0.361][π][400]
Area of sector = 144.4π cm²

Isaac paid $81 for a new surfboard. The amount paid was 60% of his total savings. How much money did he have in his savings before buying the surfboard?
Answers
Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135
The perimeter of a rectangle is 16x – 6. If the length is
5x + 2, what is the width?
Answers
Answer:
3x + 1
Step-by-step explanation:
5x + 2 × 2 = 10x + 4
do this take 16x - 6
you get 6x + 2
then divide by 2 to get the answer 3x+1
Answer:
w = 3x - 5
Step-by-step explanation:
Perimeter of a rectangle formula:
P = 2(l + w)
16x - 6 = 2(5x + 2 + w)
16x - 6 = 10x + 4 + 2w
2w = 16x - 6 - 10x - 4
2w = 6x - 10
w = 3x - 5
