Find the area of the shaded region formed by circle that touches the edges of a rectangle.
disa [49]

Answer:

266.14 \:  {cm}^{2}

Step-by-step explanation:

In case of rectangle:

Length l = 30 cm

Width w = 14 cm

Since, circle touches the edges (lengths) of the rectangle.

Therefore,

Diameter of circle = 14 cm

So, radius r = 14/2 = 7 cm

Area of the shaded region = Area of rectangle - Area of circle

= lw  - \pi {r}^{2}  \\  \\  = 30 \times 14 - 3.14 {(7)}^{2}  \\  \\  = 420 - 3.14 \times 49 \\  \\  = 420 - 153.86 \\  \\  = 266.14 \:  {cm}^{2}

The product two consecutive odd numbers is 63find the number
anygoal [31]

Answer:

These results, 7 and 9, have a product of 63, as stated.

Step-by-step explanation:

Represent the first odd number by x and the first consecutive odd number by x + 2.  Then the product of these two numbers is x(x + 2) and it equals 63.

Solve for x.  Perform the indicated multiplication, obtaining

x^2 + 2x - 63 = 0

Solve this by factoring:  (x + 9)(x - 7) = 0

Then x could be either -9 or +7.  If we let x = 7 then the first consecutive odd number is 7 + 2, or 9.  These results, 7 and 9, have a product of 63, as stated.
