Answer:
QUESTION 3
d. 3ft 3in
QUESTION 4
d. 20 in
Explanation:
To solve these problems we need to remember that the radius/radii is 1/2 the diameter.
The working is as follows :
Question 3:
Diameter of sphere = 6 ft 6 in
Radius = 1/2 diameter
Radius = 6 ft 6 in ÷ 2
Radius = 3 ft 3 in
Question 4:
Diameter of circle = 40 in
Radius = 1/2 diameter
Radius = 40 ÷ 2
Radius = 20 in
