Answer:
H = 2 S = 50 A = 50.2
Step-by-step explanation:
A=2πrh+2πr2
S = 2tr2 + 2trh
S = 2 (t x r) + (h x 2t) x r Try out ^2 for Radius
S = 2t x r^2 + r x h x 2t Rearrange back and cross out for square^2
S = 6t x 4 + 6t x r x h Cross out for t
S = 6 x 4 + 6 x 2 x h Balance out...
S= 24 + 12 x 2 Find h = 2
S = 36 + 24
S= 50 sq2
A = 50. 2
R = 2
H = 2

Area = 6.28318530718 x 4 + 6.28318530718 x 2 x 2 = 50.27sq2

We perform a simple linear regression analysis in megastat software to determine the line of best fit for both relations and their associated correlation coefficients.
Answer: 160 inches.
Step-by-step explanation:
If an octagon has 8 sides and the side length is 20 inches, 20 x 8 = 160 inches. That means she needs 160 inches of wire.
Answer:
Length = 2 ft
Width = 7/4 ft = 1.75 ft
Step-by-step explanation:
Length of room on blueprint = 1/8 *16 = 2 ft
Width of room on blueprint = 1/8 *14 = 7/4 ft = 1.75 ft
The slope of the line is 1/3
