Step-by-step explanation:

<em>Here</em><em>,</em>

<em>radius</em><em> </em><em>(</em><em>r</em><em>)</em><em>=</em><em> </em><em>2</em><em>cm</em>

<em>height</em><em>(</em><em>h</em><em>)</em><em>=</em><em>5</em><em>cm</em>

<em>now</em><em>,</em>

<em>according</em><em> </em><em>to the</em><em> </em><em>question</em><em> </em><em>we must</em><em> </em><em>find the</em><em> </em><em>surface</em><em> </em><em>area of cylinder</em><em> </em><em>so</em><em>,</em>

<em>by</em><em> </em><em>formulae</em><em> </em><em>,</em>

<em>a</em><em>=</em><em> </em><em>2.pi.r</em><em>(</em><em>r</em><em>+</em><em>h</em><em>)</em>

<em>now</em><em>,</em><em> </em>

<em>a</em><em>=</em><em> </em><em>2</em><em>×</em><em>3</em><em>.</em><em>1</em><em>4</em><em>×</em><em>2</em><em>(</em><em>2</em><em>+</em><em>5</em><em>)</em>

<em>by</em><em> </em><em>simplifying it we get</em><em>, </em>

Titus drew a circle with his compass. The circle has five central angles. Four of the angles measure 55°, 37°, 96°, and 88°. Wha
Fiesta28 [93]

Answer:

84°

Step-by-step explanation:

The circle has five central angles that together equal to 360°.

55° + 37° + 96° + 88° = 276°

Hence, to find the fifth central angle, we have to subtract 276° from 360°.

360° - 276° = 84°

The degree measure of the last central angle is 84°.

Hope this helps! :)

A pizza had 9/10 left before Lucas ate 4/5 of the pizza. How much pizza is left over
Norma-Jean [14]
1/10 is left.

Explanation:

First we need to find a common denominator. Since 5×2=10, if we multiply 4/5 by 2/2, we will be able to subtract that from 9/10.

4/5×2/2= 8/10. Then if we subtract that from the 9/10 left of the pizza, we get 1/10, the amount remaining.

Hope this helps :)

If t varies inversely as a and t= 2 when a = -4, what is t when a = 1/3?
bezimeni [28]

Answer:

t = - 24

Step-by-step explanation:

Given t varies inversely as a then the equation relating them is

t = \frac{k}{a} ← k is the constant of variation

To find k use the condition t = 2 when a = - 4

2 = \frac{k}{-4} ( multiply both sides by - 4 )

- 8 = k

t = \frac{-8}{a} ← equation of variation

When a = \frac{1}{3} , then

t = \frac{-8}{\frac{1}{3} } = - 24
