Step-by-step explanation:
The circumference of the clock will be 8.6π because its hand is the radius. In 15 minutes the hand moves a quarter of the circumference which is 2.15π or 6.571.
V = 2ab + 2ca + 2bc
2ab + 2ca = V - 2bc
2a * b + c = V - 2bc
Answer: a = v - 2bc / 2 * b + c

Answer:
7 and one-half feet squared
Step-by-step explanation:
3 x 2.5 = 7.5
Answer:
110 feet
Step-by-step explanation:
Given that,
Length of the rectangular garden = 9 1/4 feet = 37/4 feet
Width of the rectangular garden = 4 1/2 feet = 9/4 feet
We need to find the total length of fencing Mark needs to surround all 4 gardens.
The length for 1 garden = perimeter of the garden
The length for 4 garden = 4×perimeter of the garden
= 4×2(l+b)

Hence, 110 feet is the total length of the fencing Mark needs to surround all 4 gardens.
