- Diameter: d = 2r
- Area of a Circle: A = πr²
Step-by-step explanation:
<u>Step 1: Define</u>
d = 30 m
<u>Step 2: Find Area</u>
- Substitute [D]: 30 m = 2r
- Isolate <em>r</em>: 15 m = r
- Rewrite: r = 15 m
- Substitute [AC]: A = π(15 m)²
- Rearrange: A = 15²π
-3^6 = -729
-729 +(-4+7)(2)
-729 +(3)(2)
-729 + 6
-723
<em>hope it helps :)</em>
(ps: the result of -3^6 is not +729, the expression that would give this result is (-3)^6

Daisy is not correct. The shaded part is 3/50 that of the whole circle.
<h3>Is Daisy correct?</h3>
In order to determine if Daisy is correct, the area of the circle and the area of the shaded part has to be determined.
Area of the circle = = πr²
Where :
π = pi = 22/7
r = radius = 4 + 3 + 3 = 10
10²π = 100π
Area of the shaded part = 3²π = 9π
Ratio of the areas = 9π / 100π

Answer:
102.5, 12, 50
Step-by-step explanation:
This is basically asking for 41/.4 = 410/4 = 102.5
45/3.75 = 12
11/.22 = 1100/22 = 50
