Answer:

The answer to your question is     sin 45° = 0.6494      

Step-by-step explanation:

Data

sin 45° = ?

Process

Formula

       sin (15 + 30) = sin (15)cos(30) + cos(15)sin(30)

sin 15 = 0.2334

sin 30 = 0.4540

cos 15 = 0.9723

cos 30 = 0.8910

Substitution

sin(15 + 30) = (0.2334)(0.8910) + (0.9723)(0.4540)

                   = 0.2080 + 0.4414

                   = 0.6494      

None of the options

The radius is cm.
Elza [17]

Answer:

The radius is 1.75 cm, 1 3/4 cm, or 7/4 cm (all the same, just in different forms)

The circumference in terms of π is 7/2(π) cm, 3.5(π), or 3 1/2(π) cm (all the same, just in different forms)

The approximate circumference of the circle is 10.99 or 11 cm. (don't know if it's supposed to be rounded)

Step-by-step explanation:

Radius = 1/2 of the diameter, so 1/2 of 7/2 is 1.75, 1 3/4, or 7/4 cm.

Circumference in terms of pi means to not approximate pi. Circumference of circle is πd, so the exact circumference would be 7/2 pi cm, 3.5 pi cm, or 3 1/2 pi cm.

3.5 x 3.14 = 10.99. 10.99 cm ≈ 11 cm.
