Answer:

The circumference of a circle can be calculated using two formulas: C = 2πr or C = πd, where π is a mathematical constant roughly equal to 3.14, r is equal to the radius, and d is equal to the diameter.

The area of a circle can be determined using either the diameter or the radius using two alternative formulas: A = πr^2 or A = π(d/2)^2, where π is a mathematical constant roughly equal to 3.14, r is the radius, and d is the diameter.

The cost of milk is expected to raise 106% over the next year

gulaghasi [49]

Answer: about $6.90

Step-by-step explanation: 106% of 3.35

100% of 3.35 is 3.35

6% of 3.35 is 0.201

Add them together and you get 3.551

When you round to the nearest cent, you get $3.55

After add 3.55 to 3.35 and you get $6.90

The area of a triangle is found by multiplying half of the measure of its base by its height. The area of the following right tr

GarryVolchara [31]

Answer:

$\sf Area\:of\:a\:triangle=\dfrac12 \times base \times height$

Given:

area = 18 cm²
base = 6 cm
height = (h + 1) cm

Substitute the given values into the equation and solve for h:

$\sf \implies 18 = \sf \dfrac12 \times 6 \times (h+1)$

$\sf \implies 18 = \sf \dfrac62 (h+1)$

$\sf \implies 18 =3(h+1)$

expand using distributive property of addition $a(b+c)=ab+ac$ :

$\sf \implies 18=3h+3$

subtract 3 from both sides:

$\sf \implies 3h=15$

divide both sides by 3:

$\sf \implies h=5$

<u>To verify</u>:

Half of the base is 3 cm.

If h=5, then the height of the triangle is 6 cm.

Multiplying 3 by 6 is 18.

This matches the given area, so we can verify that h = 5.
