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
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.

What type of object is pictured below?
A. Segment
B. Line
C. Ray
D. Point
Answer: C. Ray
Step-by-step explanation: In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. The vertex of the angles is the starting point of the rays.

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.
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%

Step-by-step explanation:
∠ AEB and ∠ ADC are corresponding angles and are congruent, then
3x - 10 = x + 40 ( subtract x from both sides )
2x - 10 = 40 ( add 10 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25

The base of a triangle is 24 millimeters and the height is 7 millimeters. What is the area of the triangle?
Answer:
84
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.

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
