Answer:
2145 cubic inches
Step-by-step explanation:
formula for Volume of a sphere: 4/3·π·r³
V = 4/3 ·π ·(8)³
V = 4/3π · 512
V ≈ 2145
Answer:
3 : 1
Step-by-step explanation:
A jewellery shop sells 240 necklaces in a month 180 of the necklaces were sold via the shop website work out the simplest form. The rest were sold in a High Street shop.
Work out the ratio of online sales to shop sales.
Give your answer in its simplest form.
Necklace sold in the shop = 240 - 180 = 60
180 : 60
to convert to simplest form, divide both numbers by 60
3 : 1
Area of trapezoid:
A = 1/2(b1+b2)h
where
b1 = 30,
b2 = 28+12 = 40
Triangle FOG
a^2 = c^2 - b^2
a^2 = 13^2 - 12^2
a^2 = 169 - 144
a^2 = 25
a = √25
a = 5
FO = 5 so height h = FO = 5
Now you can find the Area of trapezoid
A = 1/2(b1+b2)h
A = 1/2(30 + 40) (5)
A = 1/2(70)(5)
A = 175
Answer
175 square units
