Answer:
A = 20sinθ(6 + 5 cosθ) cm²
Step-by-step explanation:
Drop perpendiculars DE and CF to AB.
Then, we have congruent triangles ADE and BCF, plus the rectangle CDEF.
The formula for the area of the trapezium is
A = ½(a + b)h
DE = 10sinθ
AE = 10cosθ
BF = 10cosθ
EF = CD = 12 cm
AB = AE + EF + BF = 10cosθ + 12 + 10 cosθ = 12 + 20cosθ
A = ½(a + b)h
= ½(12 +12 + 20 cosθ) × 10 sinθ
=(24 + 20 cosθ) × 5 sinθ
= 4(6 + 5cosθ) × 5sinθ
= 20sinθ(6 + 5 cosθ) cm²
Answer:
5%
Step-by-step explanation:
Look at the values from high school athletes (the first row of numbers) to the values of college student athletes (the second row). Since we are only looking for male percentages, ignore the women's basketball
Take any of the college values, and divide it by the high school values. After this, multiply by 100 to get a percentage
Example, 56500 ÷ 983600 = 0.05
0.05 * 100 = 5%
You will get 5% for all males sports in this table
Answer:
circumference is 18.84
area is 28.26
Step-by-step explanation:
circumference of a circle is
2πr where r is radius
= 6×3.14= 18.8
area of a circle is πr²
= 3×3×3.14
= 28.26
use π = 3.14
