Answer:
39.6 cm
Step-by-step explanation:
Applying
s = 2πrθ/360................ Equation 1
Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes
From the question,
Given: r = 9 cm, θ = 252°
Constant: π = 22/7 = 3.14
Substitute these values into equation 1
s = (2×3.14×9×252)/360
s = 39.564
s = 39.6 cm
Answer:
Face diagonal of a cube:
Step-by-step explanation:
f2 = a2 + a. Then f2 = 2a.
Even numbers end with 2,4,6,8, or 0. Thus, 28 is the even number.
First, multiply. 7x-14-4x+9. Now, add the like terms. 3x-5.
Divide 8 ft by 0.75, then divide by one third.
