Answer:
The equation of the circle is (x - 3)² + (y + 2)² = 9
Step-by-step explanation:
The form of the equation of a circle is (x - h)² + (y - k)² = r², where
- h is the x-coordinate center of the circle
- k is the y-coordinate of the center of the circle
- r is the radius of the circle
∵ The center of a circle is (3, -2)
∴ x-coordinate of the center is 3
∴ y-coordinate of the center is -2
∴ h = 3 and k = -2
∵ The radius of the circle is 3
∴ r = 3
→ Substitute them in the form of the equation above
∵ (x - 3)² + (y - -2)² = (3)²
∴ (x - 3)² + (y + 2)² = 9
∴ The equation of the circle is (x - 3)² + (y + 2)² = 9
Answer:
60 cm²
Step-by-step explanation:
a=c= 13 cm
b= 10 cm
A=?
------------
A=bh/2
- h is the leg of the right triangle with hypotenuse 13 cm and other leg 10/2 cm
- h= √13²-5²= √169-25= √144= 12 cm
The two congruent triangles that share the side AC are (c) △ADC and △CFA
<h3>How to determine the congruent triangles?</h3>
For two triangles to share the sides AC, then the points A and C must appear on the names of the triangles
In option (c), we have A and C in the names of the triangles ADC and CFA
Hence, the two congruent triangles that share the side AC are (c) △ADC and △CFA

#SPJ1
She needs to fly at 500 or higher which means that the equation needs to include
The answer is
<h2>
1. Find the SA of all of the parts:</h2>
SA of Triangle parts:
We won't be doing 5x6x1/2 because if we want the surface area of 2 areas, then we will just do normal (5x6)
(2 × 8 2) + (3 × 10 2)
SA: B x H
: 5 x 6
: 30
The surface area of the triangular parts is 30cm²
SA of Large Rectangular (in the middle) part:
SA: L x W
: 6 x 16
: 96
The surface area of the rectangular parts is 96cm²
SA of Large Rectangular (top&bottom) part:
SA: L x W x 2
: 16 x 8 x 2
: 256
The surface area of the rectangular parts is 256cm²
<h2>
2. Add all the SA's to get FINAL answer:</h2>
30+96+256=382
<h2>
So hence, The SA of the Triangular prism is: 382cm²</h2>
:D
