Answer:
area of the figure=1/2×(10+6)×3
=24 square feet
the formula for the circumference of a circle is
<span>C = 2 × π × r or C = π × D </span>
<span>If either r or D is known, you can calculate the circumference by simply substituting the known value for r or D in the formula. Use 3.14 for π.
</span>RADIUS = 10DIAMETER = 20
C IS THE ANSWER
Answer:
for a, look at my picture
b = 19.5 inches
Step-by-step explanation:
A is simple. thats my take on it, but other people coudl've drawn it differently
B is more difficult. I made triangle QRS like that so i can make a ratio.
My ratio:
QX:QY = QR:QS
8:12=13:QS
13*12 = 8*QS
156/8 = 19.5
therefore 19.5 inches
Both are not equivlant to the top speed of the model plane because caculator op.
