Answer:

A. 4.26 in^2

Step-by-step explanation:

Step 1: Find the area of the sector DBC. Here we have to use the formula.

Area of a sector = Central Angle/360 *πr^{2}

The area of the sector DBC = (54/360)*3.14*8^{2}

= 30.16

Step 2: Area of segment CFD = Area of the sector DBC - Area of the ΔCBD

= 30.17 - 25.9

Area of segment CFD = 4.27in^2

12 people are entered in a race. if there are no ties, in how many ways can the first three places come out.
prisoha [69]

Answer:

1320

Step-by-step explanation:

This is a simple permutation.

Since you start with 12 people and there are 3 winners, after every winner the number pf people available to win decrease.

First, there are 12 people, then after the first win there are 11 people, and after the 2nd win, for the third win the there are 10 people.

Thus, to find the total number of combinations, you multiply:

12*11*10=1320

Thus, there are 1320 possible combinations

Answer:

x=20

m<B=92 degrees

m<C=40 degrees

Step-by-step explanation:

48+6x-28+2x=180

20+8x=180

8x=160

x=20

(6(20)-28)=92

2(20)=40

So, x=20, m<B=92 degrees and m<C=40 degrees

A cylinder is a radius of 8cm and a volume of 800cm³ calculate it's height and total surface area
Anastaziya [24]

Answer:

3.98 cm, 602.18 cm²

Step-by-step explanation:

<u>Given:</u>

  • r= 8 cm
  • V= 800 cm³

<u>To find:</u>

  • h = ?
  • S = ?

<u>Solution:</u>

  • V = πr²h
  • h = V/πr² = 800/(π8²) = 3.98 cm
  • S = 2πr (r+h) = 16π(8+3.98) = 602.18 cm²
