(b) The globe has a radius of 28.5 cm. Find the surface area of the globe. Round your answer to two decimal places. Use:
damaskus [11]

Answer:

\boxed {\boxed {\sf  10,207.03 \ cm^2}}

Step-by-step explanation:

Surface area is the total area of the surface of an object. A globe is a sphere and the formula for calculating a sphere's surface area is:

SA= 4 \pi r^2

The radius (r) of the globe is 28.5 centimeters. Substitute this value into the formula.

  • r= 28.5 cm

SA= 4 \pi ( 28.5 \ cm)^2

Solve the exponent. Multiply the number by itself.

  • (28.5 cm)²= 28.5 cm * 28.5 cm = 812.25 cm²

SA= 4 \pi (812.25 \ cm^2)

Multiply 4, pi and 812.25 centimeters together.

SA= 12.56637061  (812.25 \ cm^2)

SA= 10207.03453 \ cm^2

Round to two decimal place or the hundredth place. The 4 in the thousandth place to the right (10207.03453) tells us to leave the 3 in the hundredth place (10207.0<u>3</u>453).

SA \approx 10207.03 \ cm^2

The surface area of the globe is approximately <u>10,207.03 centimeters squared.</u>
