Theresa is planning to make a plastic cover for her new globe to keep it from being damaged. if theresa’s new globe has a radius of 3 inches, then how much plastic will it take to cover her new globe?
a. 18(3.14) square inches
b. 72(3.14) square inches
c. 288(3.14) square inches
d. 36(3.14) square inches

D

Step-by-step explanation:

The amount of plastic needed to cover the globe is the surface area of the globe. Since a globe is a sphere, the formula is SA = 4/3 πr³. Substitute r= 3 inches.

SA = 4/3 π(3)³ = 4/3 π * 27 = 36π

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
