Answer:
3181 ft²
Step-by-step explanation:
area of the pit = {πD²/4}/2
where dia. = 90 feet
<u>plugin values into the formula:</u>
area of the pit = {π (90)²/4)/2
= 3181 ft²
Heyo! ;D
So, I think I may of heard about this topic in the past...are you working with degrees of circles? Plane angles? If so, you can use this formula to find your answer:
12° ×
÷ 180 = <u>0.2094(rad)</u>
I'm not entirely sure, however I hope this somewhat helped! If so, please lmk! Tysm and good luck!
(x-2)/6 = (3x-2)/5
(x-2)*5 = (3x-2)*6
5х-10=18х-12
13х=2
х=2/13
Answer:
use lcm

Answer:
81π for the x axis.
Step-by-step explanation:
STEP ONE: Determine the intersection.
we are given from the question that y = x^2 and y = 6x − x^2. Therefore if y = x^2, then we will have;
x^2 = 6x - x^2 ---------------------------------------------------------------------------------[1].
Solving and factorizing the equation [1] above give us x = 0 and x = 3 (that is x[6 -2x] = 0 ). Therefore, the point of intersection = (0,0) and (3,9).
<u>STEP TWO</u><em>: </em>Determine the value for the cross sectional area.
The cross sectional area= [6x - x^2]π - [x2]^2 π. --------------[2].
The cross sectional area = -12 π[x -3]x^2.
<u>STEP THREE:</u> integrate the cross sectional area taking x =3 and x =0 as the upper and lower integration limits or boundaries with respect to dx to determine the vome in the x axis.
<h3>volume =∫-12 π[x -3]x^2 dx.</h3><h3 /><h3>volume = -12 π[ (3)^4/4 - (3)^3 ] = 81π.</h3>
volume, v with respect to the x axis = 81π
