nter your answer as a decimal in the box. radians
1 answer:
Answer:
17.1972degrees
Step-by-step explanation:
length of an arc = theta/360 * 2πr
Substitute the given angle;
1.2 = theta/360 * 2(3.14)(4)
1.2 = theta/360 * 25.12
1.2/25.12 = theta/360
0.04777 = theta/360
theta = 360 * .04777
theta = 17.1972
Hence the required angle is 17.1972degrees

Step-by-step explanation:
Measure of the length of an arc of a circle is given as:

Answer:
97.96 cm
596.14 cm²
Step-by-step explanation:
sides become:
- 30 cm ⇒ 16 cm
- 25 cm ⇒ 11 cm
and added corners:
- 4*2πr/4= 2πr = 2*3.14*7 cm= 43.96 cm
then perimeter is:
- P= 2*16+2*11+43.96= 97.96 cm
the area left is:
- A= 30*25- 4*1/4*3.14*7²= 596.14 cm²
