Answer:
431.775 ft
Step-by-step explanation:
So basically we should first find the area of the rectangles which is 28 ft * 15 ft, which you get 420. Next for the semicircle, the diameter is 15 but we need the radius so you divide that by 2 to get 7.5 as the radius. Then u multiply 7.5 * π, or 3.14 to get 23.55. But since its a semicircle, or half a circle we divide 23.55 by 2 which is 11.775. Then we just add the results which is 420 ft and 11.755 ft to get a total area of 431.775 ft.

Answer:
20in²
Step-by-step explanation:
The area of a triangle is calculated using the formula A = bh/2
"A" means area.
"b" is for the base.
"h" is for the height.
It does not matter which is the base and which is the height, as long as they are perpendicular (at 90°) to each other.
5in can be the height.
8in can be the base.
Put the base and height measurements into the formula.
A = bh/2
A = (8in)(5in)/2 Multiply the measurements and the units.
A = (40in²)/2 Divide by 2
A = 20in² Area of the triangle
When you multiply units, in X in becomes in².
"in" has the exponents 1. When you multiply two "in" with exponent 1, you add the exponents. 1 + 2 = 2.
in¹ X in¹ = in¹⁺¹ = in²
Greg's daughter will have $533 in her piggy bank in a year
The money in the piggy bank would increase everyday by the amount put in it. There are seven days in a week. If he puts $0.75 everyday apart from on Sundays when we puts $5.75, the amount that would be in the piggy bank in a week is the sum of the money deposited each day.
Total amount in a week = total amount deposited from Monday to Saturday + amount deposited on Sunday
- Amount that Greg puts in 6 days : ($0.75 x 6) = $4.50
- Amount deposited on Sunday = $5.75
- Total amount = $5.75 + $4.50 = $10.25
The total amount Greg's daughter would have in a year is a function of the number of weeks in year and the total amount saved in a week
Total amount in a year = number of weeks in year x the total amount saved in a week
- Number of weeks in year = 52
- The total amount saved in a week = $10.25
$10.25 x 52 = $533
In order to determine how much Greg's daughter would have in a year, first determine how much she would have in a week. Multiply this amount by the number of weeks in a year
