What is the surface area of the prism? A. 164 yd2 B. 204 yd2 C. 240 yd2 D. 300 yd2
Answers
We have to get the areas of 5 polygons and add them together to get the surface area.
Area 1 = l * w = 5*8 = 40
Area 2 = l * w = 12 * 8 = 96
Area 3 = l * w = 13 * 8 = 104
Area 4 = bh/2 = 5*12/2 =30
Area 5 = bh/2 = 5*12/2 = 30
Area = Area 1 + Area 2 + Area 3 + Area 4 + Area 5
Area = 40 + 96 + 104 + 30 + 30
Area = 300 yard^2

The area of the sector is 20π.
Step-by-step explanation:
- The area of the circle = 100π
- The formula for area of the circle = πr²
- The central angle of the sector = (2/5)π radians
The central angle should be converted from radians to degrees.
To convert radian to degree :
1 rad × 180/π gives the degree value.
Therefore, (2/5)π × 180/π = (2/5) × 180
The π gets cancelled out.
⇒ 2× 36
⇒ 72°
To find the area of the sector :
The formula to calculate area of the sector = (central angle/360) × πr²
⇒ (72/360) × 100π
⇒ (1/5) × 100π
⇒ 20π
The area of the sector is 20π.
