The height of a tree is 62 inches. After 3 years, the height is 10 feet 8 inches. How many inches did the tree grow each year?​

the tree grew about 22 in each year

Step-by-step explanation:

62in=5ft 2in

10ft-5ft=5ft

8in - 2in= 6in

5×12 =60

60in +6in=66in

66in÷3 years = 22in a year

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

a. is correct
