Answer :
Area of sphere is given by:
Area=4πr²
but:
r=3 inches
thus
Area=4×π×3²
Area=36 π in²
Answer: 36π sq. in
Area=4πr²
but:
r=3 inches
thus
Area=4×π×3²
Area=36 π in²
Answer: 36π sq. in
Answer:
The surface of orange is 36π square inches.
Step-by-step explanation:
Given :An orange with a 3'' radius.
We have to find the surface area of orange with radius 3 inches.
Since, the orange is in shape of sphere.
So, Surface of area of orange is same as surface area of sphere.
We know,
Surface area of sphere = [tex]4\pi r^2[/tex]
Given : radius= 3 inches
Surface area of orange = [tex]4\pi\cdot (3)^2[/tex]
Surface area of orange = [tex]4\pi\cdot 9=36\pi[/tex]
Thus, The surface of orange is 36π square inches.
