Find the area of a circle with a diameter of 12 inches. use 3.14 for pi.
37.68 in2
113.04 in2
339.12 in2
452.16 in2

113.04 inch²

Step-by-step explanation:   Since area of circle=pi×r²

where r=radius of circle

 and radius=diameter/2

hence r=12/2=6 inches

hence    Area  =pi×6²

               Area  =3.14×36

                Area  =113.04 inch²

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

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
