Question

what is the surface area of this sphere? use π ≈ 3.14 and round your answer to the nearest hundredth. image of a sphere with radius 10 m square meters submit

Explanation:

Step1: Recall the formula for the surface area of a sphere.

The formula for the surface area \( S \) of a sphere is \( S = 4\pi r^2 \), where \( r \) is the radius of the sphere.

Step2: Identify the radius of the sphere.

From the diagram, the radius \( r = 10 \) meters.

Step3: Substitute the values into the formula.

Substitute \( r = 10 \) and \( \pi \approx 3.14 \) into the formula:
\( S = 4\times3.14\times(10)^2 \)

Step4: Calculate the value.

First, calculate \( (10)^2 = 100 \). Then, \( 4\times3.14 = 12.56 \). Finally, \( 12.56\times100 = 1256.00 \).

Answer:

1256.00
