Answer: 1) 36 m and 60 m^2 2) 15π/2 + 10 m and 75π/4 m^2
Step-by-step explanation:
Using the pythagorean theorem in the first question, we get that the slope is 10 m so the perimeter = 10 + 14 + 6 + 6 = 36 m and the area is
(14 + 6)*6/2 = 60 m^2
So in the next question, the arc of the circle has a length of
2π*5*3/4 = 15π/2
So the perimeter is 15π/2 + 5 + 5 = 15π/2 + 10 m
And the area is 3/4*π*5*5=75π/4 m^2
Hope it helps
Answer:
1.you don't need to calculate 25²,7²,30² and 16² because you have a formula a²-b²=(a+b)(a-b)
OP²=MO²-MP²
OP²=25²-7²
OP²=(25+7)(25-7)
=32(8)
=256
OP=√256
OP=16 cm
NP²=NO²-OP²
NP²=30²-16²
=(30+16)(30-16)
=46(14)
=144
NP=√144
=12 cm
2.draw a straight line from the angle C and name that line with CE
CE=AD and AE=CD (because AECD is a rechtangular)
So EB=10-7 =3 cm
BC²=EC²+EB²
=4²+3²
=16+9
=25
BC=√25
=5 cm
