PLEASE HELP! Daniela has a rectangular yard with a pool in the shape of a semicircle. How many square feet of grass does Daniela

GalinKa [24]

Answer:

Part 1) Area of rectangle $3,600\ ft^{2}$

Part 2) Area of semicircle $1,413\ ft^{2}$

Par 3) Total area of grass $2,187\ ft^{2}$

Step-by-step explanation:

we know that

The total area of grass is equal to the area of rectangle minus the area of semicircle

step 1

Find the area of rectangle

The area of rectangle is equal to

$A=45*80=3,600\ ft^{2}$

step 2

Find the area of semicircle

The area of semicircle is equal to

$A=\frac{1}{2}\pi r^{2}$

we have

$r=60/2=30\ ft$ -----> the radius is half the diameter

substitute

$A=\frac{1}{2}(3.14)(30)^{2}$

$A=1,413\ ft^{2}$

step 3

Find the total area of grass

$3,600\ ft^{2}-1,413\ ft^{2}=2,187\ ft^{2}$

Identify the diameter of the disc

Olegator [25]

radius = (4*10^2 + 24^2)/8*10 =

(400 + 576)/80=

976/80 = 12.2

diameter = 12.2 x 2 = 24.4

Hello!

Question 6:
To find the area of the pennant, we need to multiply the length by the width.
12 x 18 = area
12 x 18 = 216
The answer is 216 square inches.

Question 7:
The perimeter of the square is 24cm and the area is 36 square cm.
The perimeter of the rectangle is 30cm and the area is 50 square cm.
They have different perimeters and different areas.

Jill invested $20,000 in an account that earned 5.5% annual interest, compounded annually. What is the value of this account aft

noname [10]

The value of this account in 10 years is given by the formula:

FV = P*(1+r)^t

where FV is the future value in the account after 10 years(to be calculated)

P is the principal invested at the beginning

r is the interest rate and

t is the time horizon in years

Given, Invested Amount (P) = 20,000

Interest rate (r) = 5.5% = 0.055

Time horizon (t) = 10 years = 10

Substituting the formula, FV = 20,000*(1+0.055)^10 = 20,000*1.055^10 = 20,000*1.708144458 = 34,162.89

The value of this account after 10 years =$34,162.89 (Rounded to the nearest cent)
