That 10 is the diameter of the circle.
First let's find the area of the square.
A = s^2
Where 's' is the side.
A = 10^2
A = 100
Now let's find the area of the circle.
The '10' is also the diameter of the circle.
A = pi * r^2
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5
Now subtract this from the area of the square.
100 - 78.5 = 21.5
So the approximate area of the shaded region is 21.5cm^2
Answer:
No
Step-by-step explanation:
5 × 6 = 30 - 5 = 25
5 × 2 = 10 - 1 = 9
Answer:
Correct answer is
Step-by-step explanation:
As per the given diagram, we know the following details:
Height of the triangular pyramid is <em>14m</em>.
<em>Side of base</em> = <em>10m
</em>
Height of Triangular base = <em>8.7m</em>
Formula for <em>surface area of triangular pyramid</em>:

(Triangular base is shown in the dotted lines in the question figure.
The other 3 triangles are the side triangles.)
We know that,


Hence correct answer is
