Answer:
30.25π square inches
Step-by-step explanation:
You can use the formula for area in terms of circumference:
A = C²/(4π)
A = (11π)²/(4π) = (121/4)π = 30.25π . . . square inches
_____
You may be expected to find the radius first:
C = 2πr ⇒ r = C/(2π) = 11π/(2π) = 5.5 . . . inches
Then use the area formula:
A = πr² = π(5.5 in)² = 30.25π in²
Answer:
the radius is half of O
Step-by-step explanation:
Complementary angles are angles who sum to 90 degrees. So, since one angle is 13 degrees, naturally the other must equal 77. Good luck! c:
Answer:
88 cm
Step-by-step explanation:
The side of the square = 6 cm, so the shorter side of each rectangle = 6 cms.
The area of each rectangle = 36 * 1 1/3
= 36 * 4/3 = 48 cm^2
So the longer side of each rectangle = 48 / 6 = 8 cms
Therefore, the perimeter of the whole figure
= 4( shorter sides ) + 8(longer sides)
= 4*6 + 8*8
= 24 + 64
= 88 cm (answer)
F(6) = 7(6) - 4
f(6) = 42 - 4
f(6) = 38
Hope this helps!
