Answer:
139.25 m²
Step-by-step explanation:
Area of the square = 10 * 10 = 100 m²
Radius of the semicircle = 5 m
Area of the semicircle = π(5)²/2 = 39.25 m²
Total area = 100 + 39.25 = 139.25 m²
Answer:
452.39
Step-by-step explanation:
The question is asking for the area of the pool, so use the circle area formula, which is A=
. In the formula, A is the area and r is the radius. The question gives us the diameter, so divide that by 2 to get the radius. Therefore the equation is A=
, then solve to get 452.39.
Answer: I believe the answer is 800 students
Step-by-step explanation:
A circle is 360 degrees. When you have 7/10, you would multiply it by 36. This is because in the denominator, 10x36=360. 7x36? 252.
So it would be 252 degrees.
Mortgage A:
The payment is 190,000*(.0725/12)/(1 -(1 +.0725/12)^(-12*20)) ≈ 1501.71
The total of all payments is 240*1501.71 = 360,410.40, so the interest cost is this amount less the principal, or $170410.40.
Total loan cost = $2800 + 1%*190,000 +170,410.40 = 175,110.40
Mortgage B:
The payment is 190,000*(.0525/12)/(1 -(1 +.0525/12)^-240) ≈ 1280.30
The total of all payments is 240*1280.30 = 307,272.00, so the total interest cost is $117,272.00.
Total loan cost = $2800 +5%*190,000 +117,272.00 = 129,572.00
Mortgage A has a larger total cost than Mortgage B by $45,538.40
