PLEASE SOMEONE HELP ME!!! I'm stuck on this problem!!! (THE DIRECTION IS ---"Find the area of the figure")

A = 3,953 in²

You find the area of the whole triangle:
1/2bh = 1/2(63+31)(63+62) = 5875

Then subtract the missing rectangle:
lw = (62)(31) = 1922

5875 - 1922 = 3953 inches

Since you're multiplying inches by inches, it's inches².

9-43 please:/ its due tomorrow & idk what to do:////

First we find the area of the rectangle. Area of a rectangle = length * width.

The width is 19 as given. The length is the the diameter of the circle. The diameter of the circle is 2 * the radius. They give us the radius of 6.

19 * (2*6) = 19(12) = 228

Now we find the area of the circle. Half the circle however is already included in the area for the rectangle so we will use the area of the circle formula of: A = $\pi$ r² and divide it by 2.

A = $\pi$ (6)² = 36 $\pi$

Now divide it by 2 and simplify

36 $\pi$ / 2 = 18 $\pi$ . Leave this way until we are at the end.

Now put the two together.

228 + 18 $\pi$ . Put this into your calculator to see the exact answer. The one I will give is an approximation.

Area of the entire shaded area is approximately (≈) 284.549 ft² or 284.549 square feet.

The digits 1-5 are used for a set of locker codes. Suppose the digits cannot repeat. Find the number of possible two digit and t

Archy [21]

So you would do
5×4×3= 60
and
5×4=20
so, for a 3 digit code there are 60 possibilities and for a 2 digit code there are 20 possibilities.

Tublu buys a cylindrical water tank height 1.4 M and diameter 1.1 M to catch rainwater off his roof.

denis23 [38]

Complete Question:

Tublu buys a cylindrical water tank of height 1.4m and diameter 1.1m to catch rainwater off his roof. He has a full 2 liters tin of paint in his store and decides to paint the tank(not the base). If he uses 250ml to cover 1m2, will he have enough paint to cover the tank with one layer of paint? Take pie as 3.142

Answer:

Yes. It will be enough to cover the tank with 1 layer of paint. The tank requires 1.21 liters of paint.

Step-by-step explanation:

Given:

Height of cylindrical tank (h) = 1.4m

Diameter = 1.1m (radius = ½ of 1.1 = 0.55 m)

Litres of paint available = 2 liters

Rate of usage of paint = 250 ml to 1 m²

π = 3.142

Required:

Determine if the available 2 liters of paint would be enough for the painting

Solution:

Step 1: calculate the curved surface area of the cylindrical tank

Curved surface area (CSA) = 2πrh

= 2*3.142*0.55*1.4

= 4.84 m²

Step 2: Calculate how many liters of paint is required to paint the cylindrical tank having a curved surface area of 4.84 m²

If 1 m² requires 250ml (0.25 liters) of paint,

4.84m² area will require 4.84*0.25 liters

= 1.21 liters of paint.

<em>Since 2 liters of paint is available, it means the paint will be more than enough to cover the tank with 1 layer of paint.</em>
