Answer:
area of the sector = 360π cm²
Step-by-step explanation:
To calculate the area of the sector, we will follow the steps below;
First write down the formula for calculating the area of a sector.
If angle Ф is measured in degree, then
area of sector = Ф/360 × πr²
but if angle Ф is measured in radians, then
area of sector = 1/2 × r² × Ф
In this case the angle is measured in radiance, hence we will use the second formula
From the question given, radius = 15 cm and angle Ф = 8π/5
area of sector = 1/2 × r² × Ф
=1/2 × 15² × 8π/5
=1/2 ×225 × 8π/5
=360π cm²
area of the sector = 360π cm²
Answer:
32 inches: 90 feet
Step-by-step explanation:
The question is asking for a ratio of inches to feet. Since you want the scale to be an integer, we find the lowest number to multiply 6.4 inches by to get an integer. Since 6.4 inches = 32/5, multiply by 5, leaving 32 inches. However, since you multiplied 6.4 by 5, you have to multiply 18 by 5. 6.4*5 inches: 18*5 feet, or 32 inches: 90 feet.
Answer:
40 ft squared
Step-by-step explanation:
To calculate area of a rectangle, you use the formula length times width, or base times height.
5 x 8 = 40 feet squared
