Answer: in exact form: 291.5 + 30.25π cm²
correct to 2 decimal places: 386.53 cm²
Step-by-step explanation:
first you find the area of the rectangle:
= length × width
= 53 × 11
= 583 cm²
Next you find the area of the semicircle:
= π × r² (where r is the radius)
= π × (11/2)²
= 30.25π cm²
Then you find the area of the unshaded triangle:
= half × base length × perpendicular height
= 1/2 × 53 × 11
=291.5 cm²
Finally you subtract the unshaded area (the triangle) from the shaded area (not including the semicircle) then add the semicircle to your result.
= 583 (rectangle) - 291.5 (triangle) + 30.25π (semicircle)
= 291.5 + 30.25π
≈ 386.53 cm² (2 decimal places)
Answer: 38.25
Step-by-step explanation: You divide the whole number by the denominator in the fraction.
153/4 = 38.25
Well, negatives are less than zero, and the greater the number the less it is, or in this case colder, so we know that the first two are -19, and -10, then comes 0, and increases from there. So, the answer would be B. (-19, -10, 0, 15, 28)

Answer:
C) 2/9
Step-by-step explanation:
1. you add up all of the marbles (18)
2. you find how much blue marbles are out of that sum of the total marbles (4/18)
3. simplify if possible (2/9)
Answer:
1 - C (38 cm)
