<em>98 cm²</em>
- Step-by-step explanation:
<em>A(parallelogram) = PR×CD</em>
<em>252cm² = PR×18cm</em>
<em>PR = 252cm²/18cm</em>
<em>= 14 cm</em>
<em>PR = diameter => radius = d/2 = 14cm/2 = 7 cm </em>
<em>A(circle) = π×r²</em>
<em>= 22/7 × (7cm)²</em>
<em>= 22/7 × 49cm²</em>
<em>= 154 cm²</em>
<em>A(shaded) = A(parallelogram) - A(circle)</em>
<em>= 252cm² - 154cm²</em>
<em>= 98 cm²</em>
Answer:
a = 54
Step-by-step explanation:
In geometry, the angles in a triangle add up to 180.
The unmarked angle at the top of the triangle = 180 - (a+10+44)
Or you could say that same angle = 180 - 2a because it is supplementary to the exterior angle... so
2a = a + 10 + 44
2a-a = 54
a = 54
Answer:
ED and EC
Step-by-step explanation:
If the two rays which extend in the opposite direction having same endpoint is said to be opposite rays.
From the picture attached,
Rays having same endpoint E but not in the opposite directions are ED and EC.
This pair of rays meet at point E having different directions.
Similarly EA and EB is the other pair of rays having same end point (at E) but not in opposite directions.
So half of 3.1 is 1.05, so if you add the 4 to 1.05, you get 5.05, or 5005 metres- which is how far Tony’s ran
