Firstly, to calculate a price you need to change the percentage into a decimal. You do this by dividing it by 100.

30 / 100 = 0.3
The price will be 70% of the original price,
70 / 100 = 0.7,
0.7 * 53 = 37.10,

The sale price of the sweater will be $37.10.

Hope this helps!

The diameter of this beach ball is 12 inches.
Wittaler [7]

Answer:

288π or 904.78

Step-by-step explanation:

We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is \frac{4}{3} × π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.

Volume = \frac{4}{3} × π × r³

→ Let's substitute in the values

Volume = \frac{4}{3} × π × 6³

→ Simplify

Volume = \frac{4}{3} × π × 216

→ Simplify further

Volume = 288π or 904.78

Answer with detail. Please show work for all questions (worth 100 points plus ill mark brainliest) ^-^ Thanks!
polet [3.4K]

Answer:

see below

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We can find the radius from the diameter

r = d/2 = 34/2 = 17

V = (3.14) (17)^2 * 27

V =24501.42 m^3

The surface of a cone is found by

SA = pi r^2 + pi r  l where l is the slant height

We can find the radius from the diameter

r = 8/2 = 4

SA =(3.14) * 4^2 + 3.14 * 4*7

      =50.24+87.92

        138.16 in^2

The lateral surface area of a pyramid is found by taking the area of the sides

LSA = 4 * the area of a triangle

          we multiply by 4 since there are 4 sides

        = 4 * 1/2 b*h  where b is the base of the triangle and h is the height of the triangle.  (in this case it would be the slant height)

           = 2 * 8 *22

          =352 m^2
