Simplify 61+12/4-1
please

63

Step-by-step explanation:

The answer can be solved using the method of PEMDAS.  First, you should divide 12 by 4 to get 3 for that particular part.  Your equation should now be 61 + 3 - 1.  The problem can now be solved from left to right.  Add 3 from 61 to get 64 and subtract 1 from that number to get 63 as your final answer.

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
