Answer:
Step-by-step explanation:
The base of a cone is simply a circle.
The formula for the area of a circle is A = πr^2.
Example: What is the area of the base of a cone, if the radius of the base is 5 cm?
Answer: A = π(5 cm)^2 = 25π cm^2
Answer:
14 pounds
Step-by-step explanation:
Here we have to use multiplication.
Yamin purchased 6 heads of cabbage.
The weight of each cabbage = 2
First let's convert the mixed fraction 2 to improper fraction
2 =
The weight of 6 heads of cabbage = 6 x
= 114/8
= 14
We can reduce 2/8 = 1/4
= 14
Thank you.
Answer:
40°
Step-by-step explanation:
∠AOE and ∠COD are vertical angles meaning they have the same value.
<span>Let ∠ ADC = 2β
Ac and BD are perpendicular bisectors of each other ⇒⇒ (Given information)
∴ BD </span><span>bisects the angle ADC
∴ ∠ADE = 0.5 ∠ADC = β
And in ΔADE:
∵∠DEA = 90° ⇒⇒⇒ from the given information
∴∠DAE = 90° - β
And AC bisects ∠DAB </span><span><span>⇒⇒⇒ from the given information
</span>∴∠EAB = ∠DAE = 90° - β</span>
Answer:
m<T = 20°
Step-by-step explanation:
m<R = 140°
m<S = 100°
The figure given is a kite. The angles formed where two unequal sides meet are always congruent to each other. This means:
m<S = m<U = 100°
Sum of all interior angles of a quadrilateral = 360°
Therefore:
m<T = 360° - (m<S + m<U + m<R)
m<T = 360° - (100° + 100° + 140°) (substitution)
m<T = 20°
