<h3><u>S</u><u> </u><u>O</u><u> </u><u>L</u><u> </u><u>U</u><u> </u><u>T</u><u> </u><u>I</u><u> </u><u>O</u><u> </u><u>N</u><u> </u><u>:</u></h3>

According to the question,

  • Diameter of circle = 16 in

We are asked to calculate it’s circumference in terms of π.

★ Circumference of circle = 2πr

___________________________________

Let us first calculate the radius of the circle.

→ Diameter = 2 × Radius

→ 16 in = 2r

→ r = 16 in ÷ 2

→ r = 8 in

___________________________________

Substituting values in the formula of circumference,

→ C = 2πr

→ C = (2 × π × 8) in

→ C = 16π in

<u>Therefore</u><u>,</u><u> </u><u>1</u><u>6</u><u>π</u><u> </u><u>inches</u><u> </u><u>is</u><u> </u><u>the</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>

Slope = rise over run = the change in y over the change of x
if you want it to be exactly 2, then you have to make sure the equations are proportional.
 -5 - y / 6-1
so you simplify it -5-y/ 5
the answer needs to be 2 times 5,
2 x 5 = 10, so you need to add 5 because that's what you subtract from it in the end.
y = 15

What is the surface area of the rectangular pyramid below?
mezya [45]

Answer:

  A.  675 units²

Step-by-step explanation:

The formula for the surface area of a square pyramid is ...

  A = s(s +2h)

where s is the side length of the base, and h is the slant height of a face.

__

<h3>use the formula</h3>

The given pyramid has s=15 and h=15, so the surface area is ...

  A = (15)(15 +2×15) = 15(45) = 675 . . . square units

mrs jones attended a southern living Home party she purchased a vase which cost $34.99 The shipping charge was three dollars and
zhannawk [14.2K]

The total amount paid for vase is $ 41

<em><u>Solution:</u></em>

Given that

Cost of vase = $ 34.99

Shipping charge = 3 dollars

Sales tax = 8.25 % was paid on the subtotal which included the shipping charge

To find: total amount paid for vase

total amount paid for vase = Cost of vase + Shipping charge + sales tax

Let us first find the sales tax

Given that 8.25 % was paid on the subtotal which included the shipping charge

Subtotal = 34.99 + 3 = 37.99

So 8.25 % of 37.99 was paid as sales tax

\text{ sales tax } = \frac{8.25}{100} \times 37.99 = 3.1341

Therefore sales tax amount paid = $ 3.1341

total amount paid for vase = Cost of vase + Shipping charge + sales tax

total amount paid for vase = 34.99 + 3 + 3.1341 = 41.1241 ≈ 41

Therefore total amount paid for vase is $ 41
