Answer:
The surface area of the sphere is π m².
Step-by-step explanation:
The surface area of a sphere is given by the equation :
A = 4 x π x r²
where A is the surface area of the sphere, and r is the radius of the sphere.
From the question above, we know that :
diameter = 1 meter
Step 2 Calculation
We need to convert the diameter to the radius which radius is half of the diameter :
r = 1/2 . d
r = 1/2 . 1
r = 1/2 m
By substituting the parameter to the surface area equation :
A = 4 x π x r²
A = 4 x π x (1/2)²
A = 4 x π x 1/4
A = π m²
Hence, the surface area of the sphere is π m².
