Determine whether each sequence is an arithmetic sequence. If yes, then state the common difference. 7, 10, 13, 16,...

3

Step-by-step explanation:

d= term4 - term3

16-13=3

d= term2 - term1

10-7=3

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

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
