Answer:
134.1 ft²
Step-by-step explanation:
<u>Fine the area of the square first, then subtract the area of the circle to find the area of the shaded part.</u>
The area of the square
= 25²
= 625 ft²
The radius of the circle
= 25 ÷ 2
= 12.5 ft
The area of the circle
= π × 12.5²
= 490.87385...
= 490.9 ft² (rounded up to the nearest tenth)
The area of the shaded part
= 625 - 490.9
= <u>134.1 ft²</u>
Answer:
1,3

I'm guessing that this one is another complementary angle, so the equation should be 90- 30= (THE ANSWER VARIABLE). Again, complementary angles add up to 90 degrees.
Answer:
-4
Step-by-step explanation:
2x + 5 = 85
2x = 80
x = 40
3x/(10-x)
3(40)/(10-40)
120/-30 = -4
