The first part is 1325
10 x 35=350
15 x 65=975
The you add them which equals 1325
Answer:
(i) The name of the part of the circle, OQ is a radius
(ii) The radius of the sector QOR is 21 cm
Step-by-step explanation:
The given figure is a sector of the circle O
∵ Any sector of a circle formed from 2 radii and an arc
∴ OQ is a radius
(i) The name of the part of the circle, OQ is a radius
The rule of the length of an arc of a circle is L =
× 2 π r, where
- α is the angle of the sector
- r is the radius of the circle
∵ The length of the arc QR is 22 cm
∴ L = 22
∵ The measure of the angle of the arc is 60°
∴ α = 60°
∵ π = 
→ Substitute them in the rule above
∵ 22 =
× 2 ×
× r
∴ 22 =
r
→ Divide both sides by 
∴ 21 = r
(ii) The radius of the sector QOR is 21 cm
Answer:
128 ÷ 16 = 8
so 8 dog food for every dog
Convert the fractions so they both have the same denominator (bottom part of the fraction)
1/5 = 7/35
This is because 5*7=35, so 1*7=7
1/7 = 5/35
This is because 7*5=35, so 1*5 =5
Then subtract the top numbers to get the answer:
