Answer: Given radius (R) = 50
Diameter = 2R = 100
Circumference = 2πR
= 100π
= 314.15926535898
Area = πR2
= 2500π
= 7853.9816339745
Answer:
4
Step-by-step explanation:
Again using the Pythagorean Theorem:
h^2=x^2+y^2, where h is the hypotenuse of a right triangle and x and y are the side lengths. You are given that the hypotenuse is 34 ft and the base side is 16ft. Let h=34, x=16, and y=height, then you have:
34^2=16^2+y^2
y^2=34^2-16^2
y^2=1156-256
y^2=900
y=√900
y=30 ft
So the ladder will reach a spot 30 feet high on the building.
Answer: 0.185 gallons
Step-by-step explanation:
Divide 5/12 by 2 1/4
First convert the improper fraction to a proper fraction, 2 1/4 = 9/4
5/12 ÷ 9/4
= 5/12 × 4/9
= 5/27 = 0.185
Answer:
<em>{ - 2 , 8 } </em>
Step-by-step explanation:
( x² - 6x ) = 2
4² = ( x² - 6x )
x² - 6x - 16 = 0
- 6 = - 8 + 2
- 16 = - 8 * 2
( x - 8 )( x + 2 ) = 0 ⇒ 
= - 2 , 
= 8
<em>{ - 2 , 8 }</em>
