Answer:
398.2 cm²
Step-by-step explanation:
The area of the whole circle is ...
A = πr²
A = π(13 cm)² = 169π cm²
The 270° sector is 3/4 of the whole circle, so its area is ...
sector area = (3/4)(169π cm²) ≈ 398.2 cm²
Input y=2x-5 into 3x -4y
3x - 4(2x-5)
= 3x -8x +20
Answer:
-50
Step-by-step explanation:
7(3 – 2w) + 2 - 3 where w = 5
21-14w+2-3= -50
