Answer:
15.35 m²
Step-by-step explanation:
For a central angle of θ in radians, the area of a segment is ...
A = (1/2)r²(θ -sin(θ))
The central angle subtending the segment is 120°, or 2π/3 radians. Thus the segment area is ...
A = (1/2)(5 m)²(2π/3 -sin(2π/3)) = (25 m²)(π/3 -(√3)/4)
A ≈ 15.35 m² . . . . area of shaded segment
Answer:
<u>12+r</u>
Step-by-step explanation:
<em>"more than" means Addition.</em>
We need to look at 2 similar triangles
1) big one: legs - a,b, and hypotenuse - c
2)small one: legs - h,s, and hypotenuse - b.
Corresponding sides:
hypotenuse - c and hypotenuse - b,
big leg - b and big leg - s,
small leg - a, and small leg h.
?(/b(big leg, big triangle)= b(hypotenuse, small triangle )/s (big leg, small triangle)
? should be hypotenuse of the big triangle, c.
Answer is second one c.
Answer:
462 words
Step-by-step explanation:
Maxine types :
294 words ⇒ 7 minutes
Let the known number of words be x.
So,
294 words ⇒ 7 minutes
x words ⇒ 11 minutes
Therefore,
294 ⇒ 7
x ⇒ 11
Now use cross multiplication and find the value of x.
7x = 294 × 11
7x = 3234
Now divide both sides by 7.
x = 462 words.
