A circle has a circumference of 615.44615. point, 44 units. What is the radius of the circle?

Answers

Answer 1

Answer:

Answer:

The radius is 98

Step-by-step explanation:

The circumference of a circle is the distance around the edge of the circle. To find the circumference, we use the formula C = 2πr. You have the circumference so substitute C = 615.44. Then solve for r.

C = 2πr

615.44 = 2πr

98 = r

Answer 2

If m\angle CED=101 then what is m\angle CEH∠CEH

Answers

Answer:

m∠CEH = 79°

Step-by-step explanation:

From the picture attached,

∠CED and ∠CEH are the pair of linear angles.

Since, pair of linear angles are supplementary angles.

m∠CED + m∠CEH = 180°

101° + m∠CEH = 180°

m∠CEH = 180° - 101°

= 79°

Therefore, measure of angle CEH is 79°.

Triangular numbers can be represented with equilateral triangles formed by dots. The first five triangular numbers are 1, 3, 6, 10, and 15. Is there a direct variation between a triangular number and its position in the sequence? Explain your reasoning.

Answers

Hello,

$T_(1) =1\n T_(2) =3=1+2\n T_(3) =6=1+2+3\n T_(4) =10=1+2+3+4\n T_(5) =15=1+2+3+4+5\n...\n T_(n) =1+2+3+....+n= (n*(n+1))/(2) \n$

Answer: No, the triangular numbers are not a direct variation. There is not a constant of variation between a number and its position in the sequence. The ratios of the numbers to their positions are not equal. Also, the points (1, 1), (2, 3), (3, 6), and so on, do not lie on a line.

What's the lateral area of a right circular cone if the diameter of the base is 4 m and the slant height of the cone is 15m? Round your answer to the nearest whole number. A. 214m2 B. 107m2 C. 94m2 D. 188m2

Answers

We are tasked to solve for the lateral area of a right circular cone given that the base diameter measurement is 4 meters and the slant height measurement is 15 meters. To solve this problem, we need to use the formula below:
Lateral Area = pi*r (√h²+r²)
where r is half of the diameter measurement such as:
radius = r = diameter / 2
r = 4/2
r = 2 meters
Solving for the lateral area, we have it:
Lateral Area = 3.14*2 (√15²+2²)
Lateral Area = 94 m²

The answer is the letter "C".

The correct answer is:

C. 94m2

Solve the given problem. Zara is six years older than half Gary’s age. If Gary is four years old, how old is Zara?

Answers

this is a word problem so translate to math so this is asking 6+(4/2) which is 8

Gary is 4 and Zare is 6 years older then half of Gary's age in which would be 2 so then 6+2=8 so its 8
