Answer:
50.3 mm
Step-by-step explanation:
The perimeter of the shaded region = perimeter of a full circle + 2(Length)
= πd + 2(L)
diameter (d) = width = 9 mm
Length (L) = 11 mm
Perimeter of the shaded region = π*9 + 2(11)
= 50.2743339 ≈ 50.3 mm (nearest tenth)
Answer:
153m
Step-by-step explanation:
perimeter of an arc = theta/360 × 2πr
P= 17πm
theta = 20°
17πm= 20/360 × 2 × π × r
153πm = πr
r = 153m
The correct answer is B because the data points are too scattered
Hope this helped :)
Inscribed is a polygon inside a circle with all points on a given point in the circle. Circumscribed is a circle inside a polygon with any given point touching just one point on the polygon. Hope this helped.
Hi, to find the total surface area you need to first find the area of each face. In the end it will equal 906. Hope this helps and sorry if it is confusing.
