Answer:
183.26cm
Step-by-step explanation:
Radius of the Circle = 50cm
Let the point be at A
It turns forward 210 degrees to B.
Therefore, the central angle subtended by the arc AB = 210 degrees
The movement of the point from A to B will be the length of the arc AB.
The unit cost of the fencing and the cost of a bag of mulch together with
the area and perimeter of the garden give a cost sum of $36.5.
Response:
- The amount required to spend is <u>$36.5</u>
Cost of the barrier per feet (unit cost) = $0.75
Area covered by one bag of mulch = 7 square feet
Cost of one bag of mulch (unit cost) = $5
From the given diagram, we have;
Area of the garden = 8 ft. × 2 ft. + 0.5 × 8 ft. × 3 ft. = 28 ft.²
Length of fencing = 2 ft. + 8 ft. + 2 ft. + 5 ft. 5 ft. = 22 ft.
- Amount to spend = 4 bags × $5 + 22 ft. × $0.75 =<u> $36.5</u>
