<em>28x + 8</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em>Perimeter = sum of the sides</em>
<em>P = (2x + 8) + (25x - 3) + (3 + x)</em>
<em>= 2x + 25x + x + 8 - 3 + 3</em>
<em>= 28x + 8</em>
<em>Good luck ! </em>
Answer:
9 cm
Step-by-step explanation:
Use the cone volume formula, V = 
r²
Plug in the volume and radius, and solve for h, the height:
V = r²
27 = (3²)
27
= 9
3 =
9 = h
So, the height of the cone is 9 cm
You can use the Pythagorean theorem, a^2+b^2=c^2, to solve this.
b= square-root of (c^2)-(a^2)
b= square-root of (9^2)-(2^2)
b= 8.77.... which in the exact form is square root of 77.

Answer:
- Angle 1 = 139°
- Angle 2 = 41°
- x = 29; exterior angle = 131°
Step-by-step explanation:
These problems let you make use of the fact that the sum of the remote interior angles is equal to the exterior angle.
__
1. 53° +86° = ∠1
139° = ∠1
__
2. ∠2 +92° = 133°
∠2 = 133° -92°
∠2 = 41°
__
3. (x +9)° +93° = (4x+15)°
87 = 3x . . . . . . . . . . . . . . . . subtract x+15°
29 = x . . . . . . . divide by 3
The exterior angle is ...
(4x +15)° = (4·29 +15)° = 131° . . . exterior angle
Answer:
Area = πx² + x² or x²(π + 1)
Step-by-step explanation:
The area of the heart = area of a circle + area of the square
Note:
1. The 2 semicircles makes 1 full circle
2. The diameter of the circle = the side length of the square
Thus:
Area of the heart = πr² + s²
Where,
r = x
s = x
Formula for area of the heart = π(x²) + x² = πx² + x²
Area = x²(π + 1)
