An array is a visual drawing to be used in multiplication problems. For example; 1 × 2 is 2 and you draw it or visualize it like; 00
So the answer to your question would be...
000000000
000000000

000000000
000000000
000000000
000000000
000000000
000000000
000000000

The top is the array of how it would look like to your answer tour question. Also, another way to do this is (2 + 5) × 9 = 63 
And yasss your answer is 63.... ALSO

***!!! PLEASE give this a THANKS! ALSO the BRAINIEST ANSWER/QUESTION! :) :D =P =) =D

the length of an arc of a circle is 1/5 of its circumference. if the area of the circle is346.5cm²,find the angle subtended by t
dexar [7]

Answer:

72°

Step-by-step explanation:

From the question,

Area of the circle = πr²

A = πr²................. Equation 1

Where r = radius of the circle.

⇒ r = √(A/π)............. Equation 2

Given: A = 346.5 cm², π = 3.14

r = √(346.5/3.14)

r = √(110.35)

r = 10.5 cm.

Therefore,

circumference of the circle = 2πr = 2×3.14×10.5

circumference = 65.94 m

If the length of the arc(s) is 1/5 of its circumference.

Therefore, length of arc (s) = 13.188

⇒ length of arc/circumference = 13.188/65.94 =  1/5

s/2πr = θ/360

Where θ = angle substends at the center of the circle

1/5 = θ/360

θ = 360/5

θ = 72°

In triangle FGH, angle G is 30 degrees and angle H is 100 degrees. What is the measure of angle F? * 1 point 50 degrees 70 degre
serg [7]
Mark brainlist please!

Answer is 50 degrees

Since,

measure of angle F + measure of angle G + measure of angle H = 180

30 + 100 + measure of angle F = 180

Measure of angle F = 180 - 130

Measure of angle F = 50 degrees
