What is the circumference of a circle that has a radius of 10 in? Use 3.14 for π.
31.4 ft
62.8 ft
15.7 ft
314 ft
The circumference is 62.83in
Step-by-step explanation:
The formula to find the perimeter or circumference of a circle is P=2×π×r.
Step 1: Find the radius. In this case it is 10 in.
Step 2: Multiply the radius by 2 for simplicity. In this case 10×2=20.
Step 3: Multiply the last number by π. In this case, 20×3.14=62.8.
Step 4: You have the answer. Hope this helps!

Answer:
Ok so first, divide the figure into 2 triangles ABC and ADC
Then, find the area of triangle ABC, base being 10 (5+5) and height being 4
= 1/2 * bh
= 1/2 * 10 * 4
= 20 sq. units
For 2 triangles, 20 * 2 = 40 sq. units
Write the formula for the parabola.
Answer:
Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.

Will give brainlest if right
Step-by-step explanation:
Use formula for cube volume:
V=a³
Then add informations you already have and you are done.
V=0,5³
V=0,125 m³
Answer:
0.125
Step-by-step explanation:
The formula to find the volume of a cube is: V=a^3
Since we are given that one side of the cube is 0.5 m, you can take 0.5 and insert it into the formula V=a^3
V=0.5^3
V=0.125

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.
If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?
Marcellus's eyes should be 5 cm apart
If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;
Marcellus eyes are 1x far apart as Dan's eyes.
If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.
Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.
Essentially, Marcellus's eyes will be just as wide as Dan's eyes

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $1790 and his stock in Company B was worth $1000. The stock in Company A has increased 20% since last year and the stock in Company B has increased 22%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answer:
20.7%
Step-by-step explanation:
Amount of stock increased in Company A = 20% of 1790
= 0.20 * 1790 = $ 358
Investor's stock in company A this year = 1790 + 358 = $ 2148
Amount of stock increased in Company B = 22% of 1000
= 0.22 * 1000= $ 220
Investor's stock in company B this year = 1000 + 220 = $ 1220
Total amount in investor's stock account = 2148 + 1220 = $ 3368
Increased amount = 3368 - 2790 = $ 578
Increase percentage = [tex]\frac{578}{2790}*100[/tex] = 20.71
= 20.7%
Answer:
20.7%

Find the area of a semicircle.
Use a = 3.14
Answer:
157.08cm²
Step-by-step explanation:
pls brainliest
Answer:
157 cm
Explanation:
First you need to find the radius so you divide 20 by 2 (20 ÷ 2). Which will give you, our radius of 10. You take that radius and square it so 10 x 10. You will get a product of 100. Then you multiple the 100 by pi (100 x 3.14) and you will get 314. Since it's a semicircle you need to cut this 314 in half (314 ÷ 2 = 157).

Sophie is 3.5 years younger than her brother. She knows that when she is b years old, her brother is b+3.5 years old. Right now, Sophie is 11.5 years old.
How old is Sophie's brother?
Write your answer as a whole number or decimal.
Sophie's Brother's Age : b+3.5 years old
Sophie's Age : b years old
= 11.5
Sophie's Brother's Age = 11.5 + 3.5
= 15 years old
Hence, Sophie's brother is 15 years old.
