What is the answer to this in cm
1 answer:
The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.
s = 2π(3.5)(1/2) ≈ 11.00
Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.

Answer:
Step-by-step explanation:
Given: Browns have planted 3/16 tomatoes, 1/4 cabbage and 3/8 peppers.
First lets find out the total fraction of planted.
Now taking LCD for 16,4 and 8 to add up the fraction.
∴ LCD is 16
Next adding the fraction,
∴ Total fraction of planted gargantuas is
Lets take the size of gragantuas as ``1``
∴ To find the un planted fraction of gargantuas.
=
=
∴ 3/16 is the unplanted fraction of gargantuas.
