This is a word problem so translate to math so this is asking 6+(4/2) which is 8
Answer:
Step-by-step explanation:
Remark
The triangle with the shaded region makes exactly 1/4 of the entire circle. So the plan is to find the area of the circle and divide by 4. That gives you the area of the triangle and the shaded region. Then you find the area of the triangle and subtract it from what you just found.
Area of the circle
Area of the circle = pi * r^2
r = 12 cm
pi = 3.14
Area of the circle = 3.14 * 12^2
Area of the circle = 3.14 * 144
Area of the circle = 452.16 cm^2
Area of 1/4 of the circle
Area of 1/4 of the circle = (1/4)*452.16
Area of 1/4 of the circle = 113.04
Area of the triangle
b = r
h = r
b = 12 cm
h = 12 cm
Area = 1/2 b * h
area = 1/2 * 12 * 12
area = 72
Area of the shaded part
Shaded part = area of 1/4 of the circle - area of triangle
Area shaded part = 113.04 - 72 = 41.04
Answer area of shaded part = 41.04
Answer: x = 38°
Steps:
The little square in the corner tells us that the angle is 90°
x + 52 = 90
x = 90 - 52
x = 38°
Check:
x + 52 = 90
52 + 38 = 90
90 = 90 ✅

Answer: 19 3/8
Step-by-step explanation:
Add all the fractions and minus it from 28 1/2. So, we have to make all the denominators the same.
1) 3 1/4= 3 2/8
2) 1 3/4= 1 6/8
3) 4 1/8= 4 1/8 ( i multiplied the numerator and denominator by 2 to get number 1 and 2)
