A circular mirror has a diameter of 12 inches.what is the area, in square inches, of the mirror.

navik [9.2K]

Answer: The area of the mirror is 113.14 sq. inches [approx.].

Step-by-step explanation: Given that a circular can till 375 ft² of land in 15 min.

We are to find the area of the mirror in square inches.

The AREA of a circle with radius 'r' units is given by

$A=\pi r^2.$

The diameter of the circular mirror is 12 inches, so the radius of the mirror will be

$r=\dfrac{12}{2}=6~\textup{inches}.$

Therefore, the area of the circular mirror is

$A=\pi r^2=\frac{22}{7}\times 6^2=\dfrac{22\times 36}{7}=113.14~\textup{sq inches}~\textup{[approx.]}$

Thus, the area of the mirror is 113.14 sq. inches [approx.].

A teacher is making a history test composed of the same number of multiple-choice questions as short-answer questions. She estim

STALIN [3.7K]

Answer:

The inequality is $5.5n \leq 45$

Step-by-step explanation:

Total time:

The total time to complete the test is the sum of the number of multiple-choice questions multiplied by the time it takes to solve each and the number of short-answer questions multiply by the time it takes to solve each.

In this question:

Same number(n) of both.

Multiple-choice takes 2 minutes, short-answer takes 3.5 minutes. The total time is given by:

$T = 2n + 3.5n = 5.5n$

Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.?

This means that:

$T \leq 45$

$5.5n \leq 45$

The inequality is $5.5n \leq 45$
