The area of a trapezoid can be calculated with the formula a=a+b/2×h, where a and b are the lengths of the bases, and h is the height. what is the area of a trapezoid when a=2,b=6, and h=9?

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

might be the correct answer will be question number 2
