The area of the circle is 113.04 cm²
<u>Step-by-step explanation:</u>
The given information are,
- The diameter of the circle = 12 cm
- The diameter must be converted into radius.
Radius = diameter / 2
Radius = 12/2 = 6 cm
Now, the formula for area of the circle is given by πr²
where,
- r is the radius of the circle.
- π has the default value 3.14
<u>To calculate the area of circle :</u>
Substitute r=6 and π=3.14,
Area of the circle = (3.14) × (6²)
⇒ 3.14 × 36
⇒ 113.04 cm²
The area of the circle is 113.04 cm²
Im not sure but i think the answer is b
Answer:
12 shirts
Step-by-step explanation:
find the price of 2 shirts:
(1/2 x 34.98)+34.98=52.47
for every 2 shirts she buys, she pays $52.47
314.82/52.47=6
she bought 6 pairs= 12 shirts
