Please can you answer question b

Answers

Answer 1

Answer:
198 + (199*3) + (200*2) +(201*5) + (202*2) = 2604

frequency = 1 + 3 +2 + 5 + 2 = 13

201 = (2604 + x )/14
multiply both sides by 14
x = 201*14 = 2604 +x

x = 2814 = 2604 +x

subtract 2604 from both sides:

x = 2814 - 2604
x = 210 cm

height of new player = 210 cm

Answer:

I think I explained the circle one before so I'll explain the left question because I wanted some points.

here,

area of circle is πr² which is given= 12 π cm²

so πr²= 12π

r= 2√3

d= 2r= 4√3

AB is diameter so AB= 4√3

ABCD is a square of side length 15cm. APC and AQC are arcs of the circles with centres D and B. Calculate the area of the unshaded part?

Answers

The area of the shadedregion is 96.75 cm².

What is a square?

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is side²

We have,

Square:

Side = 15 cm

Area of a circle = πr²

APC and AQC are arcs of the circles with centers D and B.

If we remove 1/4 of the area of the circle from the circle we get one part of the unshaded region.

There are two similar unshaded parts.

Now,

The area of the unshaded part.

= 2 (side² - (1/4)πr²)

= 2 (15² - 1/4 x 3.14 x 15²)

= 2 x 15² (1 - 0.785)

= 2 x 225 x 0.215

= 96.75 cm²

Thus,

The area of the shadedregion is 96.75 cm².

Hello,

the area of the unshaded part is composed of 2 equal parts

Area of the square(side a) : a²
Area of the 1/4 cercle: πa²/2

the area of the unshaded part: 2*(a²-πa²/4)=a²/2 * (4-π) with a=15
Area=96,5708... (cm²)

move the decimal point two places to the left
multiply by 100
move the decimal point two places to the right
divide by 100

Answers

To change a percent into a decimal move the decimal point to places to the left so 67% would .67

To change a decimal into a percent you would do the reverse operation meaning move the decimal point to places to the right, so .89 would be 89%
