Answer:
78.5 m²
Step-by-step explanation:
The formula to find the area of a quarter of a circle: 
, where 
is the radius (diameter ÷ 2) and the 
is alterable.
1) Substitute the given values into the formula.
= 
2) Solve it.
= 
= 78.5
3) Round it off to the nearest tenth. In this case, it has already been rounded off.
Answer:
y = -1/3x + 5
Step-by-step explanation:
-1/3 is the slope
5 is the y-intercept
Answer:
60º
Step-by-step explanation:
A triangle is 180º so you do (180-60)/2 and you get that x=60.
Hope that helps :)
The answer would be 3/16 since 3*1 equals 3 and 4*4 equals 16
Answer:
Step-by-step explanation:
y = 3x - 5
m₁ = 3
The required line is perpendicular to y = 3x - 5. Let the required line's slope be m₂
m₂ = -1/m₁
m₂ = -1/3
Point (9,6)
Equation of line: y - y₁ = m(x - x₁)
y - 6 = (-1/3)(x - 9)
