Answer:
18.85 cm²
Step-by-step explanation:
The formula to find the area of a sector = θ/360 × πr²
We are given:
θ = Angle of the sector = 135°
Radius = Diameter/2
Diameter = 8cm , Hence Radius = 8cm/2 = 4cm
Hence,
Area of a sector = 135/360 × π ×(4cm)²
= 18.849555922 cm²
Approximately to the nearest hundredth = 18.85 cm²
Therefore, the area of the sector is 18.85 cm²
Answer:
Trigonometry can be used to measure the height of a building or mountains
Step-by-step explanation:
if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building. Similarly, if you have the value of one side and the angle of depression from the top of the building you can find and another side in the triangle, all you need to know is one side and angle of the triangle.
She had $100 and she gave $3 to her sister so $10-$3=$7 and her parent quadrupled her remaining dollars which was $7 so $7x4=$28 the answer is $28
The base's length is 8 and it's width is 7, so it's perimeter will be
. To find the lateral area you shoul multiply this with it's height. So,
(h is height).
