Answer:
87.92
Step-by-step explanation:
3.14(a² + ab)
= 3.14 (4² + 4 × 3)
= 3.14 (16 + 12)
= 3.14 × 28
= 87.92
Hope it helps :)

Answer:
X = 5
Step-by-step explanation:
Angles on a straight line=180°
180-151=29°
sum of angles in a triangle= 180°
11x-1+20-3+29=180
11x+20x-3-1+29=180
31x+25=180
31x=180-25
31x=155
divide both sides by 31
X=5
(11x-1)°= 55-1= 54°
(20x-3)°= 100-3= 97°
54°+97°+29°=180°
In the 
-
plane, the base has equation(s)
which is to say, the distance (parallel to the -axis) between the top and the bottom of the ellipse is
so that at any given , the cross-section has a hypotenuse whose length is 
.
The cross-section is an isosceles right triangle, which means the legs occur with the hypotenuse in a ratio of 1 to 
, so that the legs have length 
. Then the area of each cross-section is
Then the volume of this solid is
Answer:
(2, 1): Yes
Step-by-step explanation:
5x - 3y = 7
-2x + 7y = 3
(2, 1) = 5(2) - 3(1) = 7
10 - 3 = 7
7 = 7
-2(2) + 7(1) = 3
-4 + 7 = 3
3 = 3
Yes
