Answer:
38π cm
Step-by-step explanation:
The area of a circle of radius r is A = 2πr.
If the radius is 19 cm, then the area is A = 2π(19 cm), or 38π cm.
<h3><u>Answer:</u></h3>
<h3><u>Solution</u><u>:</u></h3>
we are given that , a ladder is placed against a side of building , which forms a right angled triangle . We wre given one side of a right angled triangle ( hypotenuse ) as 23 feet and the angle of elevation as 76 ° . We can find the Perpendicular distance from the top of the ladder go to the ground by using the trigonometric identity:
Here,
- hypotenuse = 23 feet
- = 76°
- Value of Sin = 0.97
- Perpendicular = ?
