Answer:
Step-by-step explanation:
To get from blue to red you need to multiply the blue dimensions by 1.5.
4*x = 6 Divide by 4
x = 6/4
x = 1.5
The surface area is a different ball game.
SA of the blue figure
Surface area of 1 side = 4 * 4 = 16
The total surface area = 16* 6 = 96
SA of the red figure
Surface area of 1 face = 6*6
Surface area of 6 faces = 6 * 36 = 216
So what's the ratio ?
Ratio = red surface area/ blue surface area
Ratio = 216 / 96 = 2.25
Notice that if you square the dimensional ratio, you get the area ratio
1.5^2 = 2.25
Step-by-step explanation:
s=(4+6t)3/2
t=2s
t is seconds
s is meters
s=(4+6×2)3/2
=(4+12)3/2
=16×3/2
s=24m
Answer:
second option
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus
(x - 2.5)² + (y - (- 3.5))² = 6², that is
(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle
The formula for perimeter is 2L + 2W and the formula for the area is L * W, since we don't know the width we will divide 35:7 = 5 and he the measurement for the width.
Now just add L + W = 12 and multiply by 2 the answer is 24
Or 2 * 7 + 2 * 5 = 24
