Answer:
<u>1) 17.5×14×64</u>
- → 1568 in³
<u>2) volume= 0.5×3.6×10×5=</u>
- → 90
<u>3) d= 13, r=13/2= 6.5, h= 19</u>
- → v= πr²h
- → π(6.5)²×19
- → 2521.91 mm³
<u>4) Base Area= a+b/2×h</u>
- → (37+15)/2×25.7 cm²
- →26×25.7 cm²
- → 668.2 cm²
- height= 20cm
- voulme = 668.2×20
- → 13364 cm²
<u>5) L×W×H</u>
- → 25×7×18
- → 175×18
- → 3150 ft³
<u>6) v=πr²h</u>
- → π(3.2²)(8)
- → 81.92π
- → 257.36 km²
hope it helps...
have a great day!!
