Answer:
16sqrt(3) units²
Step-by-step explanation:
This shape consists of 6 congruent triangles
Each angle = (6-2)×180/6 = 120
These are 6 equilateral triangles
6(½ × 8 × 8 × sin(60)) = 16sqrt(3) units²
The number was 4,654. Hope I helped! Please rate me the brainliest!!!
Answer: Space was alloted for each subject is 8 dm, 8 dm, 12 dm.
Explanation:
Since we have given the length of bulletin board =28 dm
Let the share of three subject areas be 2x,2x,3x
According to question,
so x=4 dm
Now,
Space was alloted for each subject is given as below:
First subject =
Second subject =
Third subject =
So first you would have to add 10 and 1/8 and 3 and 5/8 which is 4 and 3/4 then add 2 and 7/8 to 4 and 3/4 which is 7 and 5/8 so 7 5/8 is the answer.
Answer:
39.6 cm
Step-by-step explanation:
Applying
s = 2πrθ/360................ Equation 1
Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes
From the question,
Given: r = 9 cm, θ = 252°
Constant: π = 22/7 = 3.14
Substitute these values into equation 1
s = (2×3.14×9×252)/360
s = 39.564
s = 39.6 cm
