Answer:
20 sq in
Step-by-step explanation:
formula is (base * height)/2 so plug it in:
5*8=40
40/2=20
20 sq in
Answer: option D. 0.785
Explanation:
1) the probability will be equal to the area of the shaded region divided by the area of the rectangle:
area of the shaded region
probability = -------------------------------------
area of the rectangle
2) call r the radius of the circles (all are equal)
area of one circle = π (r^2)
area of the four circles = 4π(r^2) = area of the shaded region
3) area of the rectangle
length of the rectangle: 2r
height of the rectangle: 8r
area of the rectgangle = (2r)(8r) = 16 r^2
4) probability = 4π(r^2) /[(16)(r^2)] = π / 4
use π = 3.1416
probability = 3.1416 / 4 = 0.785
And you do not need to use the diameter given. The answer does not depend on this number.

Answer:
48 ft²
Step-by-step explanation:
The area of the green shaded part will be :
Area of the entire rectangle green shape assumed complete minus the area of the removed parts{ small rectangle + triangle }
<u>Area of the entire rectangle green shape assumed complete</u>
Area= length * width
A= l*w
A= 5ft * 12 ft = 60 ft²
<u>Area of small rectangle removed part</u>
2 * 3 = 6 ft²
<u>Area of the triangle removed</u>
A= 1/2 * b * h
A= 1/2 * 3 * 4
A= 6 ft²
<u>Area of the outdoor carpet needed for the hole</u>
<u />
60-{6+6}
60 -12 = 48 ft²
Answer:
![\frac{8}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B10%7D)
Step-by-step explanation:
![\frac{1}{2} +\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2B%5Cfrac%7B3%7D%7B10%7D)
![\frac{5}{10} +\frac{3}{10} =\frac{8}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B10%7D%20%2B%5Cfrac%7B3%7D%7B10%7D%20%3D%5Cfrac%7B8%7D%7B10%7D)
