Answer:
27
Step-by-step explanation:
Out of those numbers and assuming the equation is f(x) = 6x^2=3
f(-2)= 6(-2)^2+3
Answer:
SA = 1,176 ft².
Step-by-step explanation:
To find the surface area of the triangular prism, we can solve for the rectangular base, both triangular faces, and lateral sides separately.
For the rectangular base: (Use formula l×w)
20 × 18 = 360 ft²
For the triangular faces: (Use formula 1/2(b·h)
1/2(18 × 12) = 108 ft²
Since there are two faces, we need to double the amount.
108 × 2 = 216 ft².
Finally, solve for the lateral sides:
20 × 15 = 300 ft².
There are two sides, so:
300 × 2 = 600 ft².
Add up all of these areas:
600 + 216 + 360 = 1,176 ft²
The answer will be that it might be a square
<span>Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. i hope this helps you</span>
Answer:
263.76
Step-by-step explanation:
Assuming the shaded area is the yellow area all we must do is find the area of the small circle and subtract it from the larger circle.
To do this we can use the area of a circle equation:

first we need to find the radius of the large circle which is simply 4+6= 10
so the area would be:

then we find the area of the small circle is

next we evaluate:

Then replace pi with 3.14:
84 · 3.14 = 263.76
And you have your answer!
Hope this helps!
