Answer:
6.2 meters
Step-by-step explanation:
Use pythagorean theorem to find b:
b = √(2.8² - 2.7²) = √0.55 = 0.7 (nearest tenth)
Perimeter of triangle = sum of all its sides = 2.8 + 2.7 + 0.7
Perimeter = 6.2 meters
Let's take this problem step by step:
Step 1: First, the problem states that the caterer prepares four times as many pizzas as she usually prepares for a large party. It also states that she usually prepares six pizzas.
Step 2: 6 x 4 = 24
Step 3: The caterer estimates that each party guest will eat 1/4 of a pizza.
Step 4: 24 pizzas divided by 1/4 of a pizza is equivalent to 24/(1/4)
Step 5: You can take the reciprocal of 1/4 and multiply instead.
Step 6: 24 x 4 = 96
The answer is 96 party guests.
Answer:
(1 ) Inner curved surface area of the well is 109.9 sq. meters.
(2) The cost of plastering the total curved surface area is 4396.
Step-by-step explanation:
The inner diameter = 3.5 m
Depth of the well = 10 m
Now, Diameter = 2 x Radius
⇒R = D/ 2 = 3.5/2 = 1.75
or, the inner radius of the well = 1.75 m
CURVED SURFACE AREA of cylinder = 2πr h
⇒The inner curved surface area = 2πr h = 2 ( 3.14) (1.75)(10)
= 109 sq. meters
Hence, the inner curved surface area of the well is 109.9 sq. meters.
Now, the cost of plastering the curved area is 40 per sq meters
So, the cost of total plastering total area = 109.9 x(Cost per meter sq.)
= 109.9 x (40)
= 4396
Hence, the cost of plastering the total curved surface area is 4396.
Answer:
7:4
Step-by-step explanation:
42:24
divide both sides by 6
7:4
