<h3>Solution:</h3>

Radius = Diameter ÷ 2 = 13 ÷ 2 = 6.5 cm

Circumference = 2πr

→ Circumference = 2 × π × 6.5

→ Circumference = 13 π cm

Therefore, circumference of given circle = <u>13 π cm</u>

<em>Hope</em><em> it</em><em> helps</em><em> </em><em>you </em><em> </em>:)

Explain why 1.55 centimeters is a reasonable answer for the difference in the wingspans of the two butterflies
melamori03 [73]
The difference is referring to subtraction, so the question was most likely something like how much longer is this butterflies wings than this ones. so 4.55 might be one of the lengths and 3 might be the other, so 4.55 - 3 is 1.55.

Find the solutions to sin2(x) + cos(x) = 1, keeping 0 ≤ x &lt; 2π
frozen [14]
Sin2(x) +cos(x)=1
from the relation: (sin2(x) +cos2(x) =1 )
so , sin2(x)=1-cos2(x)
by subs. in the main eqn.
1-cos2(x) + cos(x) =1
by simplify the eqn.
cos(x) -cos2(x)=0
take cos(x) as a common factor
cos(x)* (1-cos(x))=0
then cos(x)=0 && cos(x)=1
cos(x)=0 if x= pi/2
& cos(x) = 1 if x = 0 , 2*pi
so the solution is x= {0,pi/2 , 2*pi}
