Therefore, the value of C should be (11/2)^2

<span>To square a fraction, take the square of the numerator and put it over the square of the denominator. So since 11^2=121 and 2^2=4, (11/2)^2
(11)^2/(2)^2=121/4
</span>

The area of a circle is 153.86 square meters. What is the diameter of the circle?
Yuliya22 [10]
Area of circle = πr² 

Given that area = 153.86 m², find the radius:

 153.86 = πr²

r² = 153.86 ÷ π

r² = 48.98

r = √48.98

r = 7 m

Diameter = Radius x 2 = 7 x 2 = 14 m

A stone is an old unit of weight used in Ireland and England to measure potatoes.A stone is 14 pounds and 80 stones make up half
Aneli [31]

Answer: Half of a ton equals to 1,120 pounds.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Since 80 stones make up half of a long ton, and each stone weight is 14 pounds, to obtain the number of pounds in half of a long ton we simply have to multiply the number of stones (80) by the weight of each stone (14)

Mathematically speaking:

<em>14 x 80 = 1,120 pounds </em>

Half of a ton equals to 1,120 pounds.
