Answer:
1)2(lb+bh+hl)
=2(17*12+12*8+8*17)
=2(204+96+136)
=2*436
=872 in^2
2)2*pi*r(r+h)
=2*3.14*14(14+29)
=6.28*14(43)
=6.28*14*43
=3780.56 mm^2
3)A=11*4.3+3*6 +3*8+11*3(Area of each plane figure -triangle and rectangle)
=47.3+18+24+33
=122.3cm^3
4)h*(sum of II sides)+14*8+19*8+14*8+25(Area of plane surface-trapezium,rectangle,square)
=12.1(19+5)+112+152+112+25
=12.1*24+401
=290.4+401
=691.4ft^2
Answer: 14
Step-by-step explanation:
If they hit the ball 4/8 times, that equals 1/2, so we just multiply 1/2 (or 0.5) by 28 and you get 14 :)
Answer:-3n
Step-by-step explanation:
