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:
The radius (r) of the globe is 28.5 centimeters. Substitute this value into the formula.
- r= 28.5 cm
Solve the exponent. Multiply the number by itself.
- (28.5 cm)²= 28.5 cm * 28.5 cm = 812.25 cm²
Multiply 4, pi and 812.25 centimeters together.
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).
The surface area of the globe is approximately <u>10,207.03 centimeters squared.</u>
