What is the approximate area of the shaded portion of the diagram? (Use 3.14 as an estimate for pi.)
Nadusha1986 [10]

Answer:

218

Step-by-step explanation:

first find the area of the circle-

A=\pi r^{2} \\A=\pi 10^{2} \\A=100\pi \\A=314

to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).

a^{2} +b^{2} =c^{2} \\a^{2} +16^{2} =20^{2} \\a^{2} +256=400\\a^{2} =144\\a=12

Now I know the height is 12. Find the area of the triangle

A=\frac{1}{2} bh\\A=\frac{1}{2} (16)(20)\\A=96

subtract the area of the triangle from the area of the circle

314-96=218

Please help with this area
agasfer [191]

Answer:

L = 7 W= 12

Step-by-step explanation:

Ok so we already know that a rectangle is not even so the numbers will have to be 2 diff numbers.

The length is 5 feet less then width

w*l=  84

1* 84         2* 41        3*28    4*21    6*14    7*12

84-1           41-2        28-3     21-4     14-6   12-7

83              39           25          19        8         5

So,

your equation would be l*w = 7*12
