We must find the radius so we can plug this into the formula for surface area.
Circumference =


We are going to plug this in as our radius for the most accurate answer.
The surface area of a sphere is

Surface Area =

≈ 451.93 units
It would be 66.3 because 2% Coverts to .02 then you multiply that to 65 and get 1.3 and then you add that to 65
Answer:
<em>1,860</em>
Step-by-step explanation:
FIRST:
we divide 124 by 4 because in 4 minutes he can type 124 words, and we need to figure out how many he can type in a minute.
124 divided by 4 is 31. (they can type 31 wpm)
NEXT: now we know they can type 31 wpm, we need to multiply that number by 60 because there are 60 minutes in an hour.
31 x 60 = 1,860
therefore, they can type 1860 words per hour
hope i helped have a great day/night! :'')
