Answer:
![A=7569\pi \ ft^2](https://tex.z-dn.net/?f=A%3D7569%5Cpi%20%5C%20ft%5E2)
Step-by-step explanation:
The diameter of a sphere is 87 feet.
We need to find its surface area. The formula for surface area is given by :
![A=4\pi r^2](https://tex.z-dn.net/?f=A%3D4%5Cpi%20r%5E2)
Where
r is the radius of the sphere
![A=4\pi \times (\dfrac{87}{2})^2\\\\=7569\pi \ ft^2](https://tex.z-dn.net/?f=A%3D4%5Cpi%20%5Ctimes%20%28%5Cdfrac%7B87%7D%7B2%7D%29%5E2%5C%5C%5C%5C%3D7569%5Cpi%20%5C%20ft%5E2)
So, the surface area of the sphere is equal to
.
Answer:
Obtuse Scalene
Step-by-step explanation:
Given
Sides of triangle: 6in, 5in and 8in
Required
Classify the triangle by angles and sides
Given that none of the three sides of the triangle are equal; we can conclude that the triangle is a scalene triangle.
The next is to determine what type of scalene triangle it is.... Obtuse or Right angled?
For the triangle to be a right scalene; then one of its angles must be 90 degrees
And for one of its angles to be 90 degrees, the three sides must obey Pythagoras theorem where;
<em>the square of the biggest side must be equal to the sum of the square of the other two sides</em>
In other words;
![8^2 := 6^2 + 5^2](https://tex.z-dn.net/?f=8%5E2%20%3A%3D%206%5E2%20%2B%205%5E2)
![64 := 36 + 25](https://tex.z-dn.net/?f=64%20%3A%3D%2036%20%2B%2025)
![64 \neq 61](https://tex.z-dn.net/?f=64%20%5Cneq%20%2061)
Since, the above condition doesn't apply to the sides of the triangle, then it's safe to conclude that the triangle is an obtuse scalene
C= Clarence, J= Juan, and D= Darlene
C= 3J-5
D= C/2+2
J= c

Step-by-step explanation:
How do u find the scale factor of a dilation?
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states
