Answer:

Step-by-step explanation:

JM is a diameter. 1/2 JM is the radius. 1/2 10 = 5

The radius is 5

The above statement is true if N is the center.

The semi circle has an area of pi r^2/2 = 5^2/2 * pi = 25/2 * pi

12.5 pi

The area of the other part is

(58/360) * pi * r^2 =

0.161 * pi * 5^2

0.161 * pi * 25

4.03 * pi

Now add these two parts together.

12.5pi + 4.03= 16.53 * pi.

That's one possible answer.

Another would be 16.53 * 3.14 = 51.897

If you have choices, list them.

Rama is stringing beads whose lengths are each 0.19 inches. How can rounding be used to estimate the length of a row of 9 beads?

Mice21 [21]

Since the beads are about 0.20 inches, the length of a row of 9 beads will be approximately 9 × 0.20 = 1.80 inches.

Step-by-step explanation:

According to given statement;

Length of individual stringing beads = 0.19 inches

Rounding off = 0.2 inches

Length of row of 9 beads = 9* rounded off length of individual beads

Length of row of 9 beads = 9*0.2

Length of row of 9 beads = 1.80 inches

Since the beads are about 0.20 inches, the length of a row of 9 beads will be approximately 9 × 0.20 = 1.80 inches.

Answer:

5i

Step-by-step explanation:

= $\sqrt{-1 * 25}$
= $\sqrt{-1}\sqrt{25}$
= $\sqrt{-1}$ * 5

Rule: $\sqrt{-1}$ = i

So you get i * 5 = 5i
