Answer:

A = 102 cm^2

Step-by-step explanation:

This figure is a trapezoid. The area is given by

A = 1/2 (b1+b2) *h where b1 is the base and b2 is the top

b1 = 21 b2 = (6+7) and h = 6

A = 1/2 (21+13) *6

A = 1/2 (34)*6

A = 102 cm^2

Art [367]

Answer:

18.85 inches.

Step-by-step explanation:

We have been given that the radius of a smaller circle 3 inch. We are asked to find the circumference of smaller circle.

We know that circumference of a circle is equal to $2\pi r$ , where r represents radius of circle.

$\text{Circumference of smaller circle}=2\pi (3\text{ inches})$

$\text{Circumference of smaller circle}=6\pi\text{ inches}$

$\text{Circumference of smaller circle}=18.84955592\text{ inches}$

$\text{Circumference of smaller circle}\approx 18.85\text{ inches}$

Therefore, the circumference of smaller circle is approximately 18.85 inches.

Rút gọn (x-4) (x-3) -x(x+5) +82

WINSTONCH [101]

Answer:

-12x + 94

Step-by-step explanation:

Simplify:

$\left(x-4\right)\left(x-3\right)-x\left(x+5\right)+82$

$=x^2-7x+12-x\left(x+5\right)+82$

$=x^2-7x+12-x^2-5x+82$

$=x^2-x^2-7x-5x+12+82$

$=-7x-5x+12+82$

$=-7x-5x+94$

$=-12x+94$
