Answer:
<u>14762 ft³</u>
Step-by-step explanation:
<u>Volume of top prism</u>
- V = 61 x 8 x (19 - 3)
- V = 488 x 16
- V = <u>7808 ft³</u>
<u />
<u>Volume of bottom prism</u>
- V = 61 x 38 x 3
- V = 183 x 38
- V = <u>6954 ft³</u>
<u />
Total volume = Volume (top) + Volume (bottom)
- 7808 + 6954
- <u>14762 ft³</u>
The volume of the cylinder is <span>552.92</span>
Answer:
34π/3 (= 11.3 π ) mi²
Step-by-step explanation:
(see attached for reference)
area of sector is given by:
A = (θ/360) π r²
where
θ = angle of sector (given as 255°)
r = radius (given as 4 miles)
substituting the known values into the formula:
A = (θ/360) π r²
A = (255/360) π (4)²
A = (255/360) π (16)
A = 34π/3 mi²
A = 11.3 π mi²
