What is the surface area of a dome (a half sphere) with a radius of 6 meters?
72 pi meters squared
48 pi meters squared
24 pi meters squared
144 pi meters squared

Answers

Answer: 72π meters squared.

Step-by-step explanation: Given that the radius is 6 meters, use the sphere surface area formula to find the surface area of the half-sphere;

Replace the value in the formula: A=4πr² → A=4π6²Solve the exponent first: A=4π6² → A=4π36The order of the multiples does not affect the total, so we can multiply 4 times 36 first: A=4π36 → A=144π144π is the surface area of the whole sphere, so half the sphere will be 72π. In conclusion, the surface area of the dome will be 72π meters squared.

The base of a triangle is 24 millimeters and the height is 7 millimeters. What is the area of the triangle?

Answers

Answer:

Step-by-step explanation:

area of a triangle is represented by this equation: A= 1/2(b x h)

so we plug in the base for b and the height for h to get A=1/2(24 x 7) and now we solve accordingly. 24 x 7 is 160, and 160 x 1/2 is 84.

Handy Dandy grocery is having a sale this week. If you buy a five pound bag of apples for the regular price $2.99. You can get another bag for $1.79.

Answers

Answer:

The answer is below

Step-by-step explanation:

A grocery store is having a sale this week. If you buy a 5-pound bag of apples for the regular price, you can get another bag for $1.79. If you buy a 5-pound bag of oranges at the regular price, you can get another bag for $2.49. Write an equation to find the discount for each situation.

Regular price for apples is $2.99

Regular price for oranges is $3.99

Solution:

The original price of the apples = $2.99 , price at a discount = $1.79

Discount for A= original price - price at a discount = $2.99 - $1.79

Discount for A= $1.20

x = ($1.79 / $2.99) * 100% = 59.9%

Discount in percentage = 100% - 59.9% = 40.1%

The original price of the orange = $3.99 , price at a discount = $2.49

Discount for R = original price - price at a discount = $3.99 - $2.49

Discount for R = $1.50

x = ($2.49 / $3.99) * 100% = 62.4%

Discount in percentage = 100% - 62.4% = 37.6%

The perimeter of a rectangle is 36 meters. If the length of the rectangle is 10 meters, what is the width (in meters)?

Answers

The width is 8. The length is 10 so 10+10 equals 20. You subtract 20 from 36 you get 16. 16/2 is 8. If you add 8+8+10+10 you get 36.

The width would have to be 8

Una fuente circular tiene un diámetro de 80 pulgadas conciderando que una pulgada equivale a 2.54cm cual es la medida de su ratio

It is given that a circular fountain has a diameter of 80 inches.

What is the diameter?

A diameter is a distance that passes through the center of the circle to the endpoint of a circle.

1 inches = 2.54 cm

Let 80 inches = x cm

x = 80 × 2.54 cm

x = 203.2 centimeter.

Step-by-step explanation:

We write out the question 2 1/4 - 3/4 = ?

Then you use the model A below

Next you can add on from the smaller number 3/4 being step 1

And you use model B to find step 2 + step 3 as it reminds you that there is 1/4 in total time being the smallest box out of the sum.

step 1 = 3/4 + 1/4 = 1 = 1/4 is missing in A model box

step 2 = + 1 (to make 2) = 1 is left in B model box

step 3 is + 1/4 is left in B model box

Then add the up = 1/4 + 1 + 1/4 = 1 1/2
