Planet earth has a mass of 5.9726 × 10 24 kilograms. and although 70% of the earth's surface is made of water, the water's mass is only 5 × 10 -4 percent of the earth's total mass. use scientific notation to estimate the mass of the planet's water. in your final answer, include all of your estimates and calculations.

250

step-by-step explanation:

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

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
