The area of circular garden is 615.44 feet2. What is the circumference of the garden? (Use 3.14 for .)

ella [17]

Answer:

B.)

87.92 feet

Step-by-step explanation:

Given:

Area of the circular garden $= 615.44 ft^2$

$\pi =3.14$

Finding the radius of the circle.

Area of the circle= $\pi r^2$

$615.44=\pi *r^2$

$r^2=\frac{615.44}{\pi } \\\\r^2=\frac{615.44}{3.14} \\r^2=196\\r=14 ft.$

Circumference of the garden:

$=2\pi r\\=2*3.14*14\\=87.92ft.$

Ghella [55]

Answer:

x ≈ 263.1

Step-by-step explanation:

The marked sides are the hypotenuse and the side adjacent to the given angle. The relevant trig relation is ...

Cos = Adjacent/Hypotenuse

cos(70°) = 90/x . . . . use given values

x = 90/cos(70°) . . . . multiply by x/cos(70°)

x ≈ 263.1

<em>Additional comment</em>

The mnemonic SOH CAH TOA is intended to remind you of the primary trig relations:

Sin = Opposite/Hypotenuse

Cos = Adjacent/Hypotenuse

Tan = Opposite/Adjacent

Priscilla started a part time job working at an after school program.

pav-90 [236]

Answer:

Step-by-step explanation:

The first week, she worked

$3 \times 2\frac{1}{2} = 3 \times \frac{5}{2} = \frac{15}{2}$

The second week, she worked

$3 \times 2 \frac{1}{4} = 3 \times \frac{9}{4} = \frac{27}{4}$

Total number of hours she worked over these 6 days

$\frac{15}{2} + \frac{27}{4} = \frac{57}{4} = 14\frac{1}{4}$
