Answer:

\huge\boxed{\sf h = 6.75 \ in.}

Step-by-step explanation:

<u>Given Data:</u>

Base area = A_{B} = 108 in.²

Volume = V  = 729 in.³

<u>Required:</u>

Height = h = ?

<u>Formula:</u>

V=A_{B}h

<u>Solution:</u>

For h, rearranging formula:

\displaystyle h = \frac{V}{A_{B}} \\\\h =\frac{729 \ in.^3}{108 \ in.^2} \\\\h = 6.75 \ in.\\\\\rule[225]{225}{2}

Find the area of the shaded region. Use 3.14 as an approximation.​
MA_775_DIABLO [31]

Answer:

shaded area = 113.64 cm²

Step-by-step explanation:

To find the shaded area, subtract the area of the circle from the area of the triangle.

Area of a triangle = 1/2 x base x height

⇒ area of triangle = 1/2 x 25 x 21.4 = 267.5 cm²

Area of a circle = \pi r^2 (where r is the radius)

From inspection, we can see that the diameter of the circle = 14 cm

Therefore, as the diameter = 2r, then r = 14 ÷ 2 = 7 cm

⇒ area of circle = 3.14 x 7² = 153.86 cm²

Shaded area = area of triangle - area of circle

⇒ shaded area = 267.5 - 153.86 = 113.64 cm²

I  -  \frac{ E }{ R}  = r

\frac{I R -E  }{ R}  = r
