Answer:
48,400 yd²
Step-by-step explanation:
(220+180)/2*260=52000
1/2(180)(60)=5400
So the total area is 52000+5400=57400
Basketball court=2400
Picnic area = 4200
Playground = 40x50 + 10x40=2400
2400+4200+2400=9000
57400-9000=48400
Answer:
B. 2.618 units
Step-by-step explanation:
the arc length = (5π/6) / 2π × 2×3.14×1
= 5/12 × 6.28
= 31.4/ 12
= 2.618 units
There are 3.45 meters in 345cm
Answer:
If x and a are counting numbers is x-a less then or greater than 1
The magnitude of a right angle is 90°.
we are asked to find a fraction of 90°.
one sixth as a fraction is 1/6.
therefore to find 1/6th of a right angle we can calculate as follows
1/6 of 90
when we have the 'of' function it means to multiply

numerators are multiplied by numerators and denominators multiplied by denominators

angle is 15°
therefore 1/6th of right angle is 15°
