Suface area= 2πrh+2πr²
= 2×3.14×2×15+2×3.14×2²
= 6.28×2×15+6.28×4
=188.4+25.12
=213.52
so Surface area=213.52cm
Answer:
24, 40
Step-by-step explanation:
The area of a triangle is given by the formula

where
b is the length of the base
h is the length of the height
For the 1st triangle here, we have:
b = 6 is the base
h = 8 is the height
So, the area of the triangle is

For the 2nd triangle here, we have:
b = 8 is the base
h = 10 is the height
So, the area of the triangle is

Answer:
Option 1) p ←→ q
Step-by-step explanation:
The given statement is a combination of two phrases with a connective word.
Phrase 1 - The Fratellis will be arrested.
We consider this phrase as phrase p.
Phrase 2 - If the police believe chunk.
Phrase q.
Now these statements p and q are connected with a connecting word "If only and only".
When two phrases are connected by the connecting words "Only and only if", this connecting word is called as biconditional operator.
p (connecting word) q
p ( If and only if) q
p ←→ q
Therefore, Option 1) p ←→ q is the answer.

Step-by-step explanation:
2 1/2 times 5 1/4 = 13.125
Answer:
72°
Step-by-step explanation:
The lengths 25 cm and 8 cm are the sides of the rectangle.
See the attached diagram of rectangle ABCD.
Now, let us assume the diagonal AC makes x° angle with the shorter side BC i.e.∠ BCA = x°
So, using trigonometry we can write

⇒
degrees ≈ 72 degrees {Rounded to nearest degree} (Answer)
