Answers

Answer 1
Answer: circumference=2 times pi times radius

if we use 22/7 as pi

2 times 22/7 times 14
multiply them
2 times 22/7=44/7
44/7 times 14=616/7=88
the circumfence=88 cm

What is the unknown number? 7 yards 2 ft =___?___ft

Answers

The missing number is 23 because,
there is 3 feet in 1 yard
so, 7x3=21
21+2=23 
so 7 yards and 2 feet = 23 feet
The unknown number is 23 feet because in 1 yard, there are 3 feet. So, 3 multiplied by 7 yards is 21 feet. 21 feet and the 2 other feet combined is 23 feet in total.

What is the volume of a cylinder with a radius of 7 feet and a height of 12 feet? Use 3.14 for pi. Round your answer to the nearest hundredth.A. 1,846.32 cubic feet
B. 1,950.25 cubic feet
C. 1,999.21 cubic feet
D. 2,000.31 cubic feet

Please answer asap

Answers

The volume of the cylinder to the nearest hundredth is  1,846.32 cubic feet.

A cylinder is a three-dimensional shape. It is a prism with circular edges.

Volume of a cylinder = πr²h

  • π = pi = 3.14
  • r = radius
  • h = height

3.14 x 7² x 12 = 1,846.32 cubic feet

Please find attached an image of a cylinder. To learn more about to determine the volume of a cylinder, check: brainly.com/question/12763699
Find the area of the base of the cylinder, 

A = \pi x 49

Then multiply by the height of the cylinder,

49\pi x 12 = 588\pi

then insert 3.14 for pi

588 x 3.14 = 1,846.32 cubic feet

Pls give us model to this question:Joanne earns $720 a week. She spends 1/3 of her money on groceries and household goods and 3/4 of the remaining money on rent. How much money does she spends on rent, groceries and household goods.

Answers

Rent = 360
Groceries and hhold goods = 240

Given: 
Weekly pay = 720
Groceries and household goods = 1/3 of weekly pay
Rent = 3/4 of money net from groceries.

720 * 1/3 = (720*1)/3 = 240 groceries and household goods
720 - 240 = 480 remaining money for rent
480 * 3/4 = (480*3)/4 = 1440/4 = 360 rental payment
480 - 360 = 120 remaining money.

Joanne spends 360 for rent and 240 for groceries and hhold goods.
$720 x .333= $239.76
720.00 - $239.76 = 480. 24

$480.24 x .75 ( 3/4 is the same as 75%) = $360.18
