Answer:
Area of Square= 12*12= 144
Area of Circle= πr2
Radius= 12/2= 6
Area of Circle= 3.14*6*6 =113.04
Area of shaded region= 144- 113.04 = 30.96 = 31.0 (1 dp)
The correct answer is D.
If you look at the equation you can see that the line crosses at the points
(1,5) and (-2, -4). Use this set of ordered pairs to find the slope.
(-4-5)/(-2-1) = (-9/-3) = 3
The use the point-slope formula and fill in the ordered pair (1,5) with the slope.
y - 5 = 3( x - 1)
Formula for the volume: V = 1/3 x pi x r^2 x height
Plug in known values: V = 1/3 x pi x (16.6)^2 x 5.6
Solve for V: V = 1/3 x pi x 275.56 x 5.6
V = 1/3 x pi x 1543.136
V = 1615.9682
V = 1616.0 m^3
Hope this helps!! :)
Answer:
question 2: exponential, question 3 is linear, also there is a site called desmos and that has a scientific calculatior and graphing calculator, the graphing calculator can help you with questions like these, all you have to do is put the points
Answer:
-94
Step-by-step explanation:
2( − 6) − 72 − (13 − 3)
PEMDAS
Parentheses first
2( − 6) − 72 − 10
Then multiply and divide from left to right
-12 -72-10
Then add and subtract from left to right
-94
