Answer:

Step-by-step explanation:
From the question we are told that:
Diameter 
Radius
Generally the equation for Circumference of a circle is mathematically given by


Answer:
Step-by-step explanation:
The formula for the area of a triangle is ...
A = (1/2)bh
Filling in the numbers you are given, you get ...
1500 = (1/2)(5/6h)(h)
3600 = h^2 . . . . . . . . . multiply by 12/5
60 = h . . . . . . . . . . . . . .square root
b = 5/6·60 = 50 . . . . . . base is 5/6 of height
The measures of the base and height are 50 ft and 60 ft, respectively.
Answer: The numbers are -3 and 2
Step-by-step explanation: Let x be the first number and y be the second number
then according to given statements the linear equations will be:
"Four times a number minus twice another number is -16"
"The sum of the two numbers is -1"
From equation 2:
Putting y = -x-1 in equation 1
Subtracting 2 from both sides
Dividing both sides by 6
Putting x = -3 in equation 2:
Hence,
The numbers are -3 and 2
400x=22,000
22,000/400=x
55=x Hopefully this is right, and hopefully this helps
