Answer:9/4
Step-by-step explanation:multiply 2.25 by 100 so you get 225/100 and reduce
While it says they are joined, we will have to solve them as seperate shapes then add the area at the end.
Since we have a half circle and a triangle, the formulas for the areas are as follows
Half-Circle
it is the regular circle formula, but divided by 2, since it is half the size of a regular circle
(pi*r^2)/2
Triangle
it is the formula for the area of a triangle, being base times height divided by 2
(b*h)/2
Plug in the numbers into the appropriate variables, then add. you should get a total area of 49.274 ft^2. Then you just multiply the final area by the $1.50 to get the cost of the mini gold course.
I think this story is describing a right triangle with one leg 28, hypotenuse 81 - 28 = 53 and we're asked for the other leg,
√(53² - 28²) = 45
Answer: 45 feet
Answer:
8 miles
Step-by-step explanation:
Using the Pythagorean Theorum, we put in c=√4.8^2+6.4^2, which when we solve, will be equal to 8.
(Sorry if this is incorrect)
If r=13cm, the d is double that so it is 26cm.
