Answer:
r = 6.5 inch.
Step-by-step explanation:
The given data :-
- The length of the hour hand = 4 inches.
- The height of the minute hand = 5.8 inches.
Solution:-
∵ Angle traced by hour hand in 12 hour = 360°
∴ Angle traced by hour hand in 4 hour = 
= 120°
The distance between the ends of the hand of the clock is given by ( r )
r² = (3.5)² +( 4)² - 2 x 3.5 x 4 cos ( 120⁰ ) = 12.25 + 16 + 14 = 42.25
r = 6.5 inch.
Answer:
153.94 is the area
Step-by-step explanation:
If the radius is 7p sqrt of 7p and you have your answer
The area of a circle is pi times the radius squared (A = π r²)
Answer:
x = 2
Step-by-step explanation:
'x' can represent the hypotenuse of a right triangle with a base of 4 (11-7) and a height of 2
use Pythagorean Theorem to find 'x':
2² + 4² = x²
4 + 16 = x²
x² = 20
x = 
x = 
·
x = 2
Cosec θ = 1.6981
1/sin θ = 1.6981
sin θ = 1 / 1.6981 = 0.5889
θ = arc sin 0.5889 = 36.1 degrees
ANSWER
20 units.
EXPLANATION
We want to find the distance between (-8,-8) and (4,8).
We use the distance formula:
We substitute the points into the formula to get:
We simplify to get;
The distance between the two points is 20 units.
