Answer:
20°
Step-by-step explanation:
One way of doing this is to find the constant of proportionality, k:
8k + 6k + 4k = 90° Then 18k = 90°, and k turns out to be 90/18, or 5.
Then the angles are 8(5), 6(5) and 4(5). The smallest of these angles is thus 20°
V = 576 pi cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi * (6)^2 * 16
V = pi *36*16
V = 576 pi cm^3
Answer:serval cats and 21
Step-by-step explanation:
Answer:
1.36 centimeters
Step-by-step explanation:
Given,
side length ( a ) = 17 mm
To find : Perimeter of regular octagon ( in cm )
Octagon has 8 sides.
Perimeter of regular octagon
= 8 x a
= 8 x 17
= 136 mm
1 mm = 0.1 cm
136 mm
= 136 x 0.1
= 1.36 centimeters ( cm )
Hence,
Perimeter of regular octagon is 1.36 centimeters.
