The perimeter would be the sum of the side lengths of the figure. Therefore, from the figure the perimeter would be the sum of the rectangle and half of the circle. We calculate as follows:
Perimeter = 2(pi)r / 2 + (2w + 2l)
Perimeter = pi(6/2) + 2(3) + 2(6)
Perimeter = 27.4 mm
Answer:
1/12, 30/360 and 30°
Explanation:
the fraction turns through <u>1/12</u> of the circle, as shown in the diagram.
1/12 = <u>30/360</u>, because 360 ÷ 12 × 1 = 30.
thus, the measure of the angle is <u>30°</u>.
