Answer

25.

Explanation:

Step1: Recall diameter - radius relation

The diameter $d$ of a circle is twice the radius $r$, i.e., $d = 2r$.

Step2: Substitute the given radius

Given $r=12$ mm, then $d = 2\times12$ mm. $d = 24$ mm

Answer:

24 mm

26.

Explanation:

Step1: Calculate total number of marbles

The total number of marbles $n$ is the sum of red, blue and yellow marbles. So $n=2 + 3+6=11$ marbles.

Step2: Calculate probability of red marbles

The probability $P$ of picking a red marble is the number of red marbles divided by the total number of marbles. There are 2 red marbles, so $P=\frac{2}{11}$.

Answer:

$\frac{2}{11}$

Brief Explanations:

A right - isosceles triangle has one right angle (90 degrees) and two equal sides. Option C has a right angle and two equal - length sides.

Answer:

C.

28.

Explanation:

Step1: Understand the problem

We know the large square is divided into 100 smaller squares and we need to find $\frac{3}{4}$ of 100.

Step2: Calculate the number of small squares

We use the formula for finding a fraction of a number: $\frac{3}{4}\times100=\frac{3\times100}{4}=75$.

Answer:

75

29.

Explanation:

Step1: Write each part in digits

One billion is 1000000000, two hundred eighty - four million is 284000000, two hundred four thousand is 204000.

Step2: Add them together

$1000000000+284000000 + 204000=1284204000$

Answer:

1284204000
