If all three dimensions of a triangle are doubled, then which of the following statements about its perimeter will be true? 4:1, 1:2, 2:1, 3:1. If anybody knows this please respond asap

1 : 2

Step-by-step explanation:

First situation

sides of triangle:-

a=x, b=2x, c=3x

then perimeter = a+b+c

perimeter = x + 2x + 3x

Perimeter = 6x

Second situation(sides are doubled)

sides of triangle:-

a=2x, b=4x, c=6x

then perimeter = a+b+c

perimeter = 2x + 4x + 6x

Perimeter = 12x

Ratio of first situation to second

Perimeter of first situation : Perimeter of second situation

6x : 12x

1 : 2

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
