Find the surface area of a sphere with radius 10 in. leave your answer in terms of pi.

a. 400pi square inches
b. 4,000/3pi square inches
c. 100pi square inches
d. 500/3pi square inches

A.

Step-by-step explanation:

Given: The radius of the sphere = 10 in.

The formula to calculate the surface area of the sphere is given by:-

, where r is the radius of the sphere.

For r=10 in. we have

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
