Question

Find the surface area of the sphere

Answer 1

Surface area can be calculated using the formula : 4pi*r^2

Answer 2

Pi {3.14} x R{Radius, Half the diamater}Squared.

Answer 3

so, it would be 3.14 * 10squared?

Answer 4

3.14xR^2 , so, the radius is what?

Answer 5

i got 1256.

Answer 6

Okay, so 10 is your radius. R^2 means you times 10 by 2. So, 3.14xR^2= Your answer.

Answer 7

these are my answer options:
a. 133.33π m²
b. 400π m²
c. 1600π m²
d. 4000π m²

Answer 8

would it be A?

Answer 9

surface are = 4pi*r^2
= 4pi*100
= 400 pi

Answer 10

ah, okay. thanks so much! :)
