The solution is in the attached below
Circumference=31.4yd

The original expression is given by:

The correct way to rewrite the expression is given by:

For this, we use two properties:
Associative property:
The way of grouping the factors does not change the result of the multiplication:
Commutative property:
The order of the factors does not vary the product:
Given:
Area = 150 square feet
Bases = 14 feet and 16 feet
Find the height of the trapezoid.
Let us use the formula of finding the Area of a trapezoid to get the value of its height.
A = (a+b)/2 * h
150 ft² = (14ft + 16ft)/2 * h
150 ft² = 15ft * h
150 ft² / 15 ft = h
10 ft = h
The height of the trapezoid is 10 feet.
Answer:
113.04
Step-by-step explanation:
To find the area of a circle, you multiply 3.14 times the radius squared. To find the radius, you divided the diameter by 2. You get 6. You square 6 and get 36. Multiply that by 3.14 and you'll get 113.04 as your area.
Answer:
3a^2+12a
Step-by-step explanation:
3a(4+a)
3a*4=12a
3a*a= 3a^2
