The diameter of a circle is 11 m. Find its area to the nearest tenth.

95.0 m²

Step-by-step explanation:

The formula for the area of a circle of radius r is A = πr².

Here the diameter is given and is 11 m; therefore the radius is r = (11/2) m.

Thus, the area of this circle is

A = πr² = π(11/2 m)²  = π(121/4) m², or approx. 95.0 m²

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
