The area of any circle is (pi) x (radius)² .
The area of the WHOLE circle in the question is
(pi) x (2.5 cm)²
= (pi) x (6.25 cm²) .
The full circle is made by 360° of central angles.
90° of central angle makes a pie-wedge (sector)
that's exactly one fourth of the circle, so its area
is one fourth of the area of the whole circle.
Area = (1/4) (pi) (6.25 cm²)
= (0.25) (3.14) (6.25 cm²)
= 4.906 cm² .
Rounded to the nearest tenth: 4.9 cm² .
Answer:
0
Step-by-step explanation:
note that +(- ) is equivalent to -
g(x) + (- g(x)) = g(x) - g(x) = 0
First you need to make them the say unit. I will convert the centimeters in the brochure to meters to match the table. To do this you need to divide 23 by 100 to get its meter value. that will get you .23 meters. Then divide the length of the table by how large each brochure is (1.5/.23) this will get you about 6.5. And since you can't have half a brochure on the table you will round down to 6 brochures on the table.
Answer: (-3, -8) (0, 1) (-3, -8)
Step-by-step explanation:
So in the equation, y=3x+1, 1 is the y intercept (which is where the line goes through the y intercept, so graph a point at 0,1 (that also fills out the middle of the chart. 3 is the slope of the equation so then you have to use the slope and you will find 2, 7 as a point and -3, -8 as a point.
Hope that helps! :)
