Step-by-step explanation:
Hello,
The circumference of the cake is 25(1/7), but we don't know the area of the cake.
Assuming the cake has a shape of a circle,
Circumference of a circle = 2πr
Where r = radius of the circle.
Area of a circle = πr²
But π = 22 / 7
We have to first find the value of r.
2πr = 25(1/7)
2×(22/7)×r = 25(1/7)
(44/7)r = 176 / 7
(44 × 7)r = 176 × 7
44r = 176
r = 176 / 44
r = 4 inches
Area of the circle = πr²
A = (22 / 7) × 4²
A = 22 / 7 × 16
A = 352 / 16
A = 22 (inches)²
The area of the cake is 22in²
Answer:
Step-by-step explanation:
3x + 5 ≤ -13
-5 -5
-18
3x ≤ -18
3x divide by 3. Then divide the other side by three
x ≤ -6
im not 100% sure but thats how I would do it.
9 x 3.5 = 31.5
2 x 2 = 4
2 x 2 = 4 / 2 = 2
2 x 5 = 10/ 2 = 5
31.5 + 4 + 2 + 5 = 42.5^2
