Answer:
Add
Step-by-step explanation:
When MULTIPLY exponents with same base, you Keep the base and + ADD the exponents.
For question one, you would need to use the formula pi r ^2. So first you have 4.5, which is your radius(stands for r). Then you square it, which is 20.25. Then, you multiply 20.25 with pi. Then for circumference, you do 2 x pi x the radius which is 4.5. So for area, you get 63.62. Then for circumference you get 28.27.
For question 2, it is basically the same steps but instead you a diameter, not a radius. To get the radius, divide by 2, which the radius will be 6. Then from there, the radius is 6, and you solve the question.
Answer:
8+ 33
Step-by-step explanation:
8+33=41
8 (the smaller number) times 4 equals 32.
The number 33 is one more than 32.
Hope this helps!
Answer:
234 inches
Step-by-step explanation:
Area= base x height
Height= 18 inches
Base= 13 inches
The height of a parallelogram must be perpendicular to its base, the base of this parallelogram can only be 13 inches and the height is 18 inches. Since the side lengths are not straight lines the height must be found using this method.
The height of a triangle, parallelogram and trapezoid must have a height that is perpendicular to its base. Whereas it can be found by extending the length of the base or straightening the side length that is to be the height creating a right angle.
Answer:
f=0
Step-by-step explanation:
30-f+8f=30
Combine like terms
30 +7f = 30
Subtract 30 from each side
30-30 +7f = 30-30
7f = 0
Divide by 7
7f/7 = 0/7
f = 0
