Answer:
188 meters cubed
Step-by-step explanation:
- radius = 1/2d d=6 radius =3 height 20
- formula for thia equation is 1/3 (3.14)(3^2)(20)
- (3.14)(9)(20)
- 3.14 x 9 = 28.26
- 28.26 x 20 = 565.2
- 565.2/3 = 188.40
- 188.4 round to 3sf is 188
Answer:
when x=0 y=7
when x=-1 y= 6
Step-by-step explanation:
to find x & y we can make the two x expressions equal to each other
x²+2x+7=7+x (we are going to set it equal to zero to find the roots/the x value)
x²+x=0
x(x+1)=0
x=0 x=-1 (two solutions for x)
now we just plug in these values and find the y values
when x=0 y=7
when x=-1 y= 6
(x+2)(x+1)
If you multiply those together then it will equal x^2+3x+2.
