use unitary method

for 5 it costs 330p

so for 1 choc it will cost 330/5

to get 9,

(330/5) =66

66 multiplied by 9 =594

therefore 9 will cost 594p

$5\ chock\ ices\ cost\ 330p\\
9\ chock\ ices\ cost\ x\\\\\
Ratio:\\
5-330\\
9-x\\\\Cross\ multiplication\\\\\
5x=330*9\\
5x=2970\ \ \ | divide\ by\ 5\\
x=594\\\\
9\ will\ cost\ 594p.$

PLEASE HELP ME Determine the premiter of the figure . Use 3.14 for PI Round to the nearest tenth. Numbers are 10 in and 15in

densk [106]

Answer:

5 $\pi$ +40

Step-by-step explanation:

perimeter of circle=2 $\pi$ r

so 5 is r(radius)

so 10 $\pi$ , but since it’s semicircle, you have to divide by 2, so

5 $\pi$

perimeter of rectangle=15+10+15 because you don’t count the inside, so that equals 40

so 5 $\pi$ +40

A paper container in the shape of a right circular cone has a radius of 3 inches and a height of 8 inches. Determine and state t

Scrat [10]

Given:

Radius of the cone = 3 inches

Height of the cone = 8 inches

To find:

The volume of the cone, in terms of π.

Solution:

We know that, the volume of a cone is:

$V=\dfrac{1}{3}\pi r^2h$

Putting $r=3,h=8$ , we get

$V=\dfrac{1}{3}\pi (3)^2(8)$

$V=\dfrac{1}{3}\pi (9)(8)$

$V=\dfrac{72}{3}\pi$

$V=24\pi$

Therefore, the volume of the cone is $24\pi$ .
